A series of bacterial cellulose (BC) membranes modified with viburnum-like MoS2 were successfully synthesized via a novel biomimetic design derived from the plant morphology of 3D viburnum flowers located on 1D branches. In a typical MoS2/BC composite, the BC scaffolds not only achieved high dispersion of MoS2 microflower units, but also held excellent superhydrophobic potential owing to the abundant "windows" provided by the cross-linked BC fibers. By associating the results of characterizations and the surface wettability, the relationship between the morphology and properties of MoS2/BC was carefully investigated. Surface clean MoS2/BC had excellent light-driven water evaporation rate (3.01 kg & centerdot; m(-2)& centerdot; h(-1)) under 1 sun irradiation. Besides, the bioinspired rough surface of organosilicon (POTS) modified MoS2/BC membrane exhibited superhydrophobicity with a water contact angle of 159 degrees, which helped the 3D scaffolds "stand" on the water surface like a water strider. This flexible rough surface enabled the material to possess both self-floating and self-cleaning capabilities. In addition, the synergistic effect of the viburnum-like MoS2 and the interconnected porous network of BC endows the membrane with excellent oil-water separation efficiency (still similar to 95% after 20 cycles) as well as great potential for efficient dye adsorption. Notably, the flower-like 1 T@2H-MoS2 in BC membrane could provide efficient antibacterial abilities for S. aureus and E. coli even without light irradiation. Meanwhile, possible mechanisms for the above multifunctions of the MoS2/BC membrane have been discussed. This unique biomass-derived route provided an ideal platform for further design of self-floating membrane with outstanding potential for water treatments.

To enhance photocatalytic activity, we focused on improving the efficiency of electron transport. A series of PCN-222/Zn3In2S6 composites was synthesized via combining a zirconium metal-organic framework (PCN-222) with Zn3In2S6 nanosheets with in situ growth methods. The optimized composite, designated as PCN-222/Zn3In2S6-2 (PCN/ZIS-2), showed the superior photocatalytic activity, achieving an 89% removal efficiency of chlortetracycline hydrochloride (CTC) in 180 minutes (kobs = 0.4748 min-1). Electron paramagnetic resonance (EPR) and free radical trapping experiments verified that superoxide anion (center dot O2-) and holes (h+) are the primary active species involved in the degradation process. Additionally, we analyzed the plausible degradation pathways of CTC through a liquid chromatograph-tandem mass spectrometer (LC-MS). An ecotoxicological assessment of byproducts from CTC implied that these degradation pathways can lower both acute and chronic toxicity. These results offer a promising approach for reducing antibiotic pollution in water and pave the way for developing efficient photocatalytic materials for environmental cleanup.

Nowadays, with the shortage of fresh water, 3D composite evaporators have been widely adopted for solardriven interfacial evaporation. However, the performance of most conventional solar evaporators has been hampered by their structural shortcomings, which made it difficult to achieve high evaporation rates. On top of these issues, several other headaches have plagued the field, including poor interfacial bonding, mediocre water transport capabilities, and pesky salt buildup. Here, we developed a composite sponge evaporator with circumferential superhydrophobic sides and a central superhydrophilic layer. The superhydrophilic layer provided evaporation area (with the top serving as the evaporation surface) and forms a 3D water transportation network to guarantee a steady water supply. It was mainly composed of polyurethane (PU) sponge, polydopamine (PDA), lithium chloride (LiCl), and acidified carbon nanotubes (ACNTs), which are chelated and ultrasonically modified. The superhydrophobic layer, which provided evaporator self-floating capability and protection against corrosive contamination, was modified by polydimethylsilane (PDMS) side spraying. After modification of LiCl, ACNTs and PDMS further enhanced the superhydrophilicity, photo-thermal effect and superhydrophobicity of PU sponge more severe. The composite sponge evaporator with superhydrophobic sides and superhydrophilic center can reach 2.04 kg & sdot;m- 2 & sdot;h- 1 under one sunlight irradiation, with superhydrophobic properties and a contact angle of up to 157 degrees. In addition, the composite sponge evaporator with superhydrophobic sides and superhydrophilic center can realize the efficient purification of dye-containing wastewater, and the outdoor evaporation experiments further demonstrated the potential practical application of this evaporator.

The photo-enzyme synergistic strategy, which integrates photocatalytic and nanozymatic functions within a single material, represents a promising yet challenging frontier for antibiotic degradation. A two-step calcination method was employed to synthesize 2D g-C3N4 (CN) with fewer stacking layers. Inspired by the intricate layered structure of caladium, we fabricated a 2D/2D bio-inspired heterostructured nanozyme, CuO/CN, via an in-situ synthesis strategy. The optimized CuO/CN-3 composite demonstrated optimal photo-enzyme synergistic activity, achieving 95.1% degradation of oxytetracycline (OTC) under visible light, significantly outperforming its individual components (16.8% for CN and 53.7% for CuO). A synergy factor of 1.0836 quantitatively confirmed the cooperative effect. Moreover, the system achieved outstanding antibacterial performance against E. coli, an effect which is attributed to the ternary synergy of its intrinsic peroxidase-like (POD) activity, H2O2 activation, and photoexcitation. Comprehensive characterization revealed that the enhanced efficacy originates from a direct Z-scheme electron transfer mechanism at the heterojunction interface. This unique pathway effectively separates charge carriers, preserves high redox potentials, and facilitates the simultaneous generation of center dot O2-and center dot OH radicals from photo-enzyme synergistic pathways. Furthermore, the material showed excellent stability over multiple cycles, maintaining high efficiency across a broad pH range. This work provides a novel design paradigm for advanced environmental remediation platforms through the successful integration of bio-inspired architecture with photo-enzyme synergistic degradation.

In this study, a highly selective MOF-BiOBr/CdIn2S4 (MOF-BiOBr/CIS) heterostructure with CdIn(2)S(4 )nanosheets grown in situ on the tubular structure derived from Bi-MOF-based BiOBr was successfully constructed using a hydrothermal method. Under simulated solar light without sacrificial or photosensitizing agents, the 20-MOFBiOBr/CIS composite exhibited excellent photocatalytic CO2 performance, achieving production rates of 30.18 mu mol g(- 1) h(- 1) for CO and 1.50 mu mol g(- 1) h(- 1) for CH4. Compared to pure MOF-BiOBr and CdIn2S4, the CO production rates were increased by approximately 9 and 116 times, respectively. It was revealed that the 20MOF-BiOBr/CIS composite with rich oxygen vacancy exhibited close interfacial contact and efficient charge transfer. The formation of MOF BiOBr/CdIn2S4 heterojunction thereby provided efficient CO2 photocatalytic reduction. The CO selectivity of 20-MOF-BiOBr/CIS reached 83.4 %, and the MOF-BiOBr/CIS heterojunction exhibited good stability over multiple cycles. Furthermore, a mechanism for enhanced photocatalytic CO2 reduction by the MOF-BiOBr/CIS heterojunction was also proposed.

Rapid charge separation and transfer is the key scientific problem in photocatalysis. The construction of S-scheme heterojunction is one of the effective strategies to promote charge separation and maintain the strong redox properties. Herein, the NiO, K0.2WO3, and NiWO4 ternary double S-scheme K0.2WO3/NiO/NiWO4 heterojunction (W/NiO) was created by a one-step molten salt method. Ultraviolet-visible (UV-Vis) diffuse reflectance spectra, photoluminescence (PL) spectra, photoelectrochemistry tests, and other analyses revealed that the double S-scheme heterostructure broadened the spectral response range of NiO and promoted its separation of photocarriers. Compared with pristine NiO, the modified double S-scheme heterojunction enhanced the surface adsorption of water molecules and the accumulation of intermediate product of HCOO−, and optimized the CO2 reduction system, realizing the improved CO yield of 373 μmol·g−1·h−1 in Ru(byp)32+/ethanolamine of CO2 reduction system. This study indicates that double S-scheme heterojunction could facilitate efficient photogenerated charge transfer and separation, thereby achieving high activity and selectivity for CO2 photoreduction. Our work provides a reference for the one-step construction of double S-scheme heterojunction.

The flexible physical sensors have the advantage of pliability and extensibility and can be easily twisted or curved. The development of flexibility from rigidity has significantly increased the application situations for sensors, especially in intelligent robots, tactile platforms, wearable medical sensors, bionic devices, and other fields. The research of membrane-based flexible physical sensors relies on the development of advanced materials and technologies, which have been derived from a wide range of applications. Various technical methods and principles have gradually matured according to the different applications and materials used. The first section of this review discusses membrane substrates and functional materials, summarizing the development of flexible physical sensors. According to the technical sensing principles, the review is concerned with the state of research on physical sensing platforms. Lastly, the difficulties and chances for the design of emerging membrane-based flexible physical sensors in the coming years are presented.

Superior selective adsorption of organic dye is still a big challenge in the process of dye wastewater treatment. Meanwhile, low-price and environmentally friendly biomass-based adsorbents show huge potential in the fields of separation and purification. In this study, we adopted the “hydrolysis–calcination method” to develop a novel in situ anchoring strategy for ultrasmall TiO2−x on carbonized bacterial cellulose (CBC), which was derived from natural bacterial cellulose. Notably, 3D networks of porous CBC played a dual role for both providing hydrolytic sites and controlling the oxygen vacancies (Vo) of TiO2−x. As for the single-dye adsorption, the TiO2−x/CBC had a strong adsorption ability (101.4 mg/g) for removing methylene blue (MB), which was much higher than that of methyl orange (MO), malachite green (MG), rhodamine B (RhB), and tetracyclines (TC). Moreover, under the optimized carbonization temperature (Tc) of 300 °C, the TiO2−x/CBC-300 exhibited an outstanding separation efficiency of 97.07% for the MB/MO solution. Detailed analysis confirmed that Tc was a key regulator for adjusting the Vo concentration, which directly influenced the surface charge density and, further, the separation efficiency of TiO2−x/CBC. Additionally, the used adsorbent could be easily regenerated from washing by ethanol. After 4 regenerations, the adsorption efficiency declined only by 6.9% after 20 min and 13.6% after 120 min adsorption, respectively. Ultimately, this oxygen vacancy-rich TiO2−x/BC system illuminated good prospects for mixed dye wastewater adsorption and separation.

This study successfully synthesized novel S-scheme SCN/BWO heterojunction composites through the coupling of sulfur-doped porous g-C3N4 (SCN) with Bi2WO6 (BWO). The incorporation of sulfur atoms effectively modulated g-C3N4's electronic structure, extending its visible-light absorption range to 490 nm while effectively optimizing its specific surface area and pore structure. The optimized SCN/BWO composite demonstrated outstanding photocatalytic performance under light irradiation, achieving 92 % oxytetracycline (OTC) degradation within 120 min while following first-order reaction kinetics. Furthermore, the SCN/BWO composite still maintained 84 % degradation activity after four consecutive cycles. Electron spin resonance spectroscopy identified & sdot;O2- and & sdot;OH as the primary reactive species. The synergistic effects of sulfur doping and S-scheme heterojunction construction were systematically validated through photoelectrochemical measurements and interfacial charge transfer analysis. These findings provide both a practical solution for antibiotic wastewater treatment and a strategic approach for designing high-performance photocatalytic systems in environmental applications.

Nanoenzyme materials for photocatalysis are highly promising as they combine light-induced redox reactions with enzyme-like activity. In this study, a nanoenzyme material composed of bismuth metal and Bi2MoO6 was manufactured using a one-step hydrothermal method, significantly enhancing the photocatalytic CO2 reduction activity upon the addition of H2O2. The nanoenzyme material benefited from the built-in electric field (IEF) between Bi and Bi2MoO6, which was adjusted through Ohmic contact, thereby lowering the interface charge impedance and improving photocatalytic performance. Furthermore, the addition of H2O2 facilitates the redox cycling of the Bi0/Bi3+ redox couple, releasing relevant electrons for photocatalytic reduction. We explored the reaction pathways and mechanisms using in situ infrared spectroscopy, ultraviolet photoelectron spectroscopy (UPS), and density functional theory (DFT) calculations. It can be found that the best Bi/Bi2MoO6 sample produced CO at a rate of 53.65 mu mol & sdot;g- 1 & sdot;h-1 with selectivity as high as 99 %. This study demonstrated that the Ohmic contact paves a new pathway for future photo-enzyme synergistic catalytic technology in addressing environmental challenges.

Wool fabrics are susceptible to issues related to felting as a result of their surface scales, which significantly impact their usability. Traditional chlorinated shrink-proof finishing is effective but it produces organic halogen pollutants, which cause significant environmental risks. This study aimed to develop an effective and eco-friendly wool shrink-proof finishing process with an innovative combination of lithium bromide (LiBr), glycerol monomercaptoacetate (GMT), and protease (Savinase Ultra 16 XL). These ingredients work synergistically to precisely remove wool scales through a two-stage '' steam-batch '' process. The study systematically investigated the synergistic mechanisms of LiBr-induced microexpansion of fiber cortex, GMT cleavage of disulfide bonds, and hydrolysis of scale keratins by proteases. The combined use of 10 g/L LiBr, 10g/L GMT, and 6 U/mL protease endowed the wool fabric with a promising shrink-resistance property, achieving a felting shrinkage from 11.58 to 2.88% and a fabric strength retention rate of 95%. Compared to the traditional maceration method, this treatment system significantly reduces water and energy consumption while meeting the standards of machine washing. This innovative steam-batch system reduces water use by around 80% compared to traditional maceration. By molecular-level synergy of swelling-reduction-hydrolysis, it overcomes the contradiction between efficiency, environmental protection, and cost inherent in the traditional protease shrinkage prevention process.

The widespread use of antibiotics has inflicted significant environmental damage, prompting global concern and the urgent need for effective remediation strategies. In this study, by designing the structure and interface functionality on the basis of the different work functions, we developed a novel S-Scheme MnIn2S4 @BiVO4 heterojunction via electrostatic self-assembly, displaying the heightened photocatalytic performance in the breakdown of tetracycline hydrochloride (TC) upon visible light irradiation. The removal rate of superior MnIn2S4 @BiVO4 heterojunction was 1.83 and 3.55 times higher than that of individual components MnIn2S4 and BiVO4, respectively. By offering a substantial contact area between the catalyst and the reaction solution, the heterogeneous interface boosts the activation and degradation of pollutants. Furthermore, the photothermal effect expedites the degradation reaction. Capturing agent experiments and ESR investigations identified center dot O2- and center dot OH as the dominant reactive species driving this degradation process and an analysis of intermediates by HPLC-MS with a notable reduction in the toxicity of the degradation products was conducted to explore a potential degradation pathway for TC. The heightened photocatalytic efficacy of the heterojunction is credited to the S-scheme charge transfer mechanism, which boosts the utilization of charge separation, as evidenced by in-situ XPS and DFT calculations. This study offers novel perspectives on the development of S-scheme heterojunction to improve the photocatalytic degradation of persistent organic pollutants.

The conversion of CO2 into hydrocarbon fuels through photocatalytic technology contributes to a sustainable carbon cycle. However, the use of noble metals and photosensitizers in previous studies has raised costs while the slow charge transfer rates during the photocatalytic process have diminished CO2 conversion efficiency. Therefore, this study investigated a core-shell Bi2MoO6@COF photocatalyst constructed by combining Bi2MoO6 nanoflower balls with the organic covalent framework TpPa-2-COF, which facilitated the photocatalytic reduction of CO2 under water vapor conditions. Additionally, the Z-scheme heterojunction formed between Bi2MoO6 and TpPa-2-COF promoted interfacial charge transfer, enhancing the separation efficiency of electrons and holes. The optimized Bi2MoO6@COF photocatalyst exhibited excellent catalytic performance in CO2 reduction reactions, achieving a CO reduction rate of 12.71 mu mol center dot g- 1 center dot h- 1 and a CH4 reduction rate of 5.5 mu mol center dot g- 1 center dot h- 1, which were approximately 2.73 times and 1.42 times higher than those of Bi2MoO6, respectively. Furthermore, the active species capture experiment, electron paramagnetic resonance (EPR) and photoelectrochemical techniques were employed to propose the photocatalytic mechanism of CO2 reduction for asprepared Z-scheme Bi2MoO6@COF heterojunction.

The photocatalytic reduction of hexavalent chromium Cr(VI) under visible light has gained considerable attention due to its relevance to environmental remediation. In this study, Ho-doped In2S3 photocatalysts were synthesized via a photodeposition method to improve the Cr(VI) reduction performance. The characterizations of the synthesized catalysts were performed using various techniques, including X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and UV-vis diffuse reflectance spectroscopy, which confirmed the successful doping of holmium and provided insights into the material's structures and optical properties. Subsequent experiments demonstrated that the Ho-doped In2S3 exhibited enhanced photocatalytic activity with the reaction rates 1.74 and 1.98 times higher than that of undoped In2S3 at Cr(VI) concentrations of 10 and 20 mg/L, respectively. It could be attributed to improving charge separation and light absorption efficiency, ultimately leading to higher reduction rates of Cr(VI) in aqueous solutions. Trapping experiments confirmed that electrons were the dominant reactive species in the photoreduction process. Furthermore, DFT calculations showed that Ho incorporation modulated the electronic structure, facilitating photoinduced charge transfer. These findings offer a useful reference for the rational design of rare-earth-doped metal sulfide photocatalysts for environmental applications.

Photocatalytic CO2 reduction has significant potential in driving carbon fuel conversion. However, the majority of photocatalysts face challenges such as limited product selectivity, poor catalytic behavior, and bad cycle stability. In this paper, an in situ solvothermal method is proposed to synthesize BiOBr/UiO-66(Zr/Ce) composites. During this process, bimetallic UiO-66(Zr/Ce) is modified onto BiOBr, leading to a notable enhancement in the efficiency of photocatalytic CO2 reduction. Under simulated solar conditions, the optimized 10-BiOBr/UiO66(Zr/Ce) showed a CO yield of 94.89 mu mol center dot g-1 center dot h-1 with an 82.89 % selectivity. Notably, the electron consumption rate (Relectron) of 228.98 mu mol center dot g-1 center dot h-1 exceeded that of BiOBr and UiO-66 (Zr/Ce) by factors of 10.2 and 10.4, respectively. Meanwhile, the 10-BiOBr/UiO-66(Zr/Ce) composite demonstrated excellent stability over multiple catalytic cycles. The superior performance of the BiOBr/UiO-66(Zr/Ce) heterojunction stems from its close interfacial contact, which promotes interfacial electron transfer and space charge separation. In addition, the common mechanism of Ce4+/Ce3+ redox cycling and S-scheme heterojunction greatly maintains the strong redox capacity of the photogenerated carriers. This study demonstrates its great potential in photocatalytic CO2 reduction and provides a new strategy for designing stable and efficient catalysts.

The quick recombination of charge carriers and photocorrosion problems severely limit the hydrogen production performance of photocatalysts. Defect engineering is regarded as an effective approach to address these issues. In this paper, Mn0.3Cd0.7S with sulfur vacancy-rich was prepared by modulating the sulfur source (TAA), and its hydrogen evolution rate was 14.47 mmol center dot h-1 center dot g-1, a 6.3-fold improvement relative to the sulfur vacancy-poor Mn0.3Cd0.7S-P. The sulfur vacancy-rich alpha-Ni(OH)2/Mn0.3Cd0.7S composites were constructed by via hydrothermal method. Under visible light (lambda >= 420 nm), the alpha-Ni(OH)2/Mn0.3Cd0.7S-100 showed outstanding H2-evolution rate of 104.27 mmol center dot h-1 center dot g-1, a 7.2-fold increase over that of Mn0.3Cd0.7S. In addition, cycling tests confirmed excellent stability. The findings revealed that the introduction of alpha-Ni(OH)2 onto Mn0.3Cd0.7S was proven to accelerate the separation and thus significantly elevating the hydrogen evolution performance under light irradiation. This work could offer novel insights into utilizing metal hydroxide cocatalysts and sulfur defects to boost photocatalytic H2 generation.

Addressing global freshwater scarcity, solar-driven interfacial evaporation (SDIE) technology has garnered significant attention due to its sustainability and economic advantages. However, challenges including salt accumulation, substantial heat loss, and biofouling still persist when treating the water in nature. Herein, we developed a BM/BPMC Janus aerogel evaporator composed of a hydrophilic top layer and a hydrophobic bottom layer. This aerogel with a self-floating capability, reduced water evaporation enthalpy, enhanced anti-biofouling properties, salt resistance, and efficient thermal localization. Its hydrophilic top layer, fabricated by embedding MoS2@MWCNTs-OH within a bacterial cellulose (BC)/polyethyleneimine (PEI) matrix, exhibits synergistic photothermal-antibacterial functionality. The hydrophobic insulating bottom layer, constructed from silanized BC, achieves an ultralow thermal conductivity of 0.036 Wm(-1)K-1, enabling highly efficient thermal localization. Vertically aligned microchannels ensure rapid water supply and salt reflux. Synergistically, the positively charged surface of the hydrophilic layer also induces a Donnan effect, significantly enhancing system salt resistance. Furthermore, this cationic evaporator concurrently achieves highly selective adsorption of anionic dyes (>97.8 % removal for MO/CR). Hydroxyl/amino functional groups enriched within the hydrophilic layer markedly reduce evaporation enthalpy by lowering the activation energy of water molecules. Under 1 kW m(-2) solar irradiation, the evaporator achieves a water evaporation rate of 2.78 kgm(-2)h(-1) and an energy conversion efficiency of 113.2 %. This study presents a novel strategy for efficient desalination and synergistic contaminant removal in complex aqueous environments.

In this paper, a MOFs-derived S -scheme ZnO/BiOBr heterojunction photocatalyst was constructed by a one-step calcination method. It was found that the dodecahedral ZnO was well attached to the BiOBr hollow rods in ZnO/ BiOBr composites, which could simultaneously introduce oxygen vacancies and enhance interfacial interactions. The photocatalytic CO 2 reduction results exhibited that ZnO/BiOBr, without adding any sacrificial agent and photosensitiser, produced CO and CH 4 at rates of 21.13 mu mol center dot g - 1 center dot h - 1 and 2.2 mu mol center dot g - 1 center dot h - 1 under simulated sunlight, with a CO selectivity of 74.34 %, which was 6.35 and 4.07 times higher than that of the original BiOBr as well as the original ZnO 4.14 and 1.98 times, respectively. The optimised ZnO/BiOBr has excellent photocatalytic CO 2 reduction performance. The ZnO/BiOBr photocatalyst has excellent stability after 5 cycles. The unique heterostructures and matched energy band potentials between ZnO and BiOBr provided close interfacial contacts, a large number of active sites and effective charge transferred for photocatalytic CO 2 reduction. Furthermore, the mechanism of photocatalytic CO 2 reduction for S -scheme ZnO/BiOBr heterojunction was also proposed. Therefore, the MOFs-derived ZnO/BiOBr composites had the potential to be used as photocatalyst for CO 2 reduction, providing a rational design idea for solar energy -driven CO 2 conversion of MOFs-structured photocatalysts.

The conversion of CO2 into value-added fuels via photothermal-photocatalytic synergy offers a sustainable route for carbon neutrality. This study constructs an efficient heterojunction catalyst through multi-scale structural engineering, encapsulating ZIF-67-derived Co@C nanocages within a three-dimensional honeycomb-like g-C3N4 matrix (NCN). The optimized Co@C-NCN achieves a CO2 reduction rate of 102.22 mu molg(-1) h(-1) under simulated solar irradiation 10.11-fold higher than pristine NCN. Key synergistic mechanisms are revealed. Interfacial charge dynamics are optimized by an amorphous-crystalline transition zone at g-C3N4/carbon/Co interfaces, enabled by pi-pi stacking between NCN's heptazine rings (sp(2)-pi-delocalized) and the carbon layer. This mitigates lattice stress and accelerates charge migration. The amorphous carbon layer functions as an electronic buffer, directing electrons along a g-C3N4 -> carbon -> Co pathway to suppress recombination, enhancing CO2 adsorption and coupling. Localized high-temperature zones (>573 K) generated by confined heat within Co nanocrystals, synergized with waveguide light-trapping effects from the honeycomb architecture, significantly accelerate CO2 reaction kinetics at Co active centers through enhanced charge-heat transfer. This work provides a rational design strategy for photothermal-assisted photocatalysts with optimized charge-heat synergy.

The rapid recombination of photogenerated electrons and hole pairs, the low hydrogen evolution activity of single photocatalysts, and the severe issue of photo-corrosion significantly affect the performance of photocatalytic hydrogen evolution. Through heterojunction engineering to build high-performance semiconductor photocatalyst for water cracking photocatalytic hydrogen evolution is an effective way to solve the above problems. Here, Mn0.3Cd0.7S nanoparticles were loaded onto NiMoO4 nanorods by mechanical agitation, thereby constructing a series of efficient and stable Z-type NiMoO4/Mn0.3Cd0.7S heterojunction photocatalysts. The 30 %-NiMoO4/Mn0.3Cd0.7S exhibits the most optimal hydrogen precipitation performance (70.24 mmol h- 1 g- 1), marking a 4.7-fold increase compared to pure Mn0.3Cd0.7S. The formation of this heterojunction significantly enhances the separation and migration of photogenerated electron-hole pairs, thereby boosting the photocatalytic hydrogen production efficiency. Additionally, incorporating NiMoO4 enhances the transfer of photogenerated holes from Mn0.3Cd0.7S to NiMoO4, effectively mitigating the photocorrosion of Mn0.3Cd0.7S and contributing to the exceptional stability of NiMoO4/Mn0.3Cd0.7S. This work provides a reasonable way to construct heterojunction to promote hydrogen evolution.
