Poor efficiency and selectivity hinder CO2 reduction for fuel production from sustainable energy. Herein, we report notable product selectivity control of CO2 reduction reaction (CO2RR) by a newly developed organic-semiconductor-rGO cathode film (PDPP/rGO), which effectively regulates the production of CO, CO/H-2, acetone, and methanol by photocatalysis (PC), electrocatalysis (EC), and electrophotocatalysis (EPC), respectively. Notably, EPC CO2RR produces methanol with high selectivity and Faradaic efficiency (FE > 60%) at an ultralow cell voltage of -0.16 V-RHE and visible-light irradiation (lambda > 400 nm) without any sacrificial agents or metal assistance. EPC promotes an ultralow reduction potential (-2.37 V-RHE, < -1.9 V-RHE for CO2/CO2 center dot-), ensuring continuous generation of CO2 center dot-. In situ Attenuated Total Reflection-Surface Enhanced Infrared Absorption Spectroscopy (ATR-SEIRAS) and theoretical simulations reveal that the hydrogen-bonding interactions allow better complex structures between carbon-oxygen intermediates and the amide group in PDPP, strengthening multiple-electron transfer and proton addition to reductive intermediates. This dual catalytic- and composition-based selectivity control for CO2RR into liquid fuels represents the forefront of catalytic selectivity and reductive potential control by organic semiconductors. Furthermore, the electrophotocatalytic approach to achieving an ultralow reduction potential provides a new application direction and mechanism for electrochromism based on organic semiconductors.

Engineering the local strain field and coordination environment of Pt sites offers an effective route to regulate their electronic structure and optimize adsorption of oxygenated intermediates, thereby enabling the development of active low-Pt catalysts for future proton exchange membrane fuel cells (PEMFC). Herein, we prepare a PtCoNi medium-entropy alloy with an optimized mixing entropy of 1.07R and a low Pt content of 8.15 wt% through a one-step solvothermal route. The random incorporation of Co/Ni atoms generates continuously distributed lattice compression and anisotropic strain fields across the Pt lattice, due to the varied Pt-metal coordination environment. Theoretical calculations further reveal multicenter d-d hybridization and enhanced strain-electronic coupling, leading to a pronounced downshift of the Pt 5d band center and consequently optimizing the adsorption of oxygen reduction reaction (ORR) intermediates. As a result, the prepared PtCoNi/C (Pt content = 1.63 wt%) delivers an outstanding half-wave potential of 0.92 VRHE and a record-breaking mass activity (MA) of 2.109 A mg Pt-1 in 0.1 M HClO4, with astable electrochemically active surface area (ECSA) retention of 97.5% after successive 20,000 cycles. Finally, the PtCoNi catalyst has superior performance in PEMFC (Pmax = 1.96 W cm-2) with H2-O2 feeding, superior to that of state-of-the-art Pt/C. This work is a practical endeavor of constructing a medium-entropy alloy, offering a promising design pathway to developing exceptional low-Pt catalysts for PEMFC.

Effects of secondary coordination regulations for ORR on dual-atom catalysts are clarified over fabricated CoNx + FeNy moieties with P/S-coordination in outer coordination shells of metal atoms, which modulates the electronic asymmetry of dual-metal sites and effectively boosts the ORR catalytic activity.
Fine-tuning the interfacial electronic interaction and surface reactivity of S-scheme heterojunctions is critical for advancing their photocatalytic performance. This study employs density functional theory calculations to systematically investigate the effects of transition metal (TM = Cr, Mn, Fe, Co, and Ni) doping at distinct sites of a CdS/ZnO S-scheme heterojunction: the surface (TMs), the interface (TMi), and co-doping at both sites (TMs+i). The results demonstrate that all doping configurations concurrently enhance both interfacial electron transfer and the hydrogen evolution reaction dynamics. The augmentation of electron transfer across the interface is primarily driven by TM doping at the interface, which reduces the work function of CdS and enlarges the Fermi level discrepancy with ZnO, leading to an enhancement trend of TMs+i > TMi > TMs. Conversely, the optimization of hydrogen adsorption free energy (Delta G(H*)) is chiefly governed by surface TM doping, which downshifts the p-band center of S atoms and weakens the S-H bond, resulting in an improvement trend of TMs+i > TMs > TMi. Remarkably, the co-doping configuration exhibits a pronounced synergistic effect, outperforming any single-site doping in optimizing both properties. Furthermore, a clear periodic trend is identified: the promotional effect of TM doping, from Cr to Ni, progressively diminishes for both charge separation and surface reaction, which is linked to the increasing work function and S p-band center. This work highlights the significant potential of a multi-site doping strategy for the synergistic engineering of charge transfer and surface reactions in S-scheme heterojunctions, offering valuable theoretical insights for the precise design of high-efficiency photocatalysts.
Abstract The large-scale production of sustainable aviation fuels (SAFs) heavily relies on hydrogen supply, while traditional hydrogen storage and delivery suffer from safety risks and high cost. Hydrogen peroxide (H2O2) is regarded as a promising hydrogen carrier, which can be produced on-site through a green electrochemical two-electron oxygen reduction reaction (2e– ORR). Herein, oxygen, nitrogen co-modulated carbon (O-NC) catalysts were fabricated by doping N dopants and oxygen-containing functional groups (OFGs). The pyrrolic N is revealed to jeopardize the electronic structure of the NC catalyst, and the OFGs can further regulate the NC matrix for 2e– ORR. As a result, the optimized O-NC-5 catalyst exhibits an excellent H2O2 selectivity of over 80% in both alkaline and neutral electrolytes. After further optimizing Nafion content, catalyst loading, and operating conditions of O-NC-5-based gas diffusion electrodes, the assembled flow cell can deliver a high H2O2 yield of 3.4 mol gcat–1 h–1 and Faradaic efficiency of above 90%, with robust stability over 12 h. This work reveals the synergistic effects of N dopants and OFGs toward 2e– ORR performance and offers a feasible strategy to develop high-performance carbon electrocatalysts and practical electrode systems for green H2O2 production, which supports the SAF synthesis.
The anion exchange membrane water electrolysis (AEMWE) offers a promising prospect for large-scale hydrogen electro-generation. Nevertheless, current AEMWE is still criticized by large overpotentials and poor anti-reverse current capability of the anodic oxygen evolution reaction (OER). The key challenge lies in tailoring adsorption evolution mechanism (AEM) to lattice oxygen mechanism (LOM), thereby circumventing the overpotential limitation caused by inherent scaling relationship. Here, we designed and fabricated a flexible CC-NCNTs-FeNi catalyst by integrating a hydrophobic carbon nanotube network with hydrophilic FeNi layered double hydroxides (LDH) on carbon cloth (CC), with the interface-induced formations of N-doped LDH and Fe/Ni single-atomic sites. Within lab-made AEMWE setups, the catalyst achieves unprecedented OER performance, rendering 100 mA cm-2 with an overpotential of 250 mV for 100 h. Meanwhile, interface-induced atom exchange endows the catalyst with catalytic multi-functionality, enabling a superior robustness for anti-reverse currents in on-off cycling. The in-situ characterizations and theoretical simulations collectively confirm that N-doping modulates Ni 3d band center and enhances Ni-O covalency, thus favoring a transition from AEM to LOM-dominated pathway for OER.
Designing efficient S-scheme photocatalysts for simultaneous H2 evolution and organic oxidation is highly desirable for sustainable energy conversion. Herein, a novel SnS2/CdS S-scheme heterojunction loaded with transition metal single atoms (TM = Pt, Pd, Au) was constructed. Systematic density functional theory (DFT) calculations are performed to investigate the geometric structure, electronic properties, and the mechanisms of surface H adsorption and lactic acid (LA) oxidation reactions. The results reveal that in the heterojunction, electrons transfer from CdS to SnS2 through interfacial Cd-S bonds, forming a stable composite structure, while the TM single atoms are stabilized by forming TM-S bonds with surface S atoms. The incorporation of TM atoms enhances the interfacial electron transfer. Notably, the TM atoms anchored on the CdS surface effectively modulate the p-band center of neighboring S atoms, thereby weakening the S-H bond and optimizing the H adsorption-desorption equilibrium. Concurrently, those on the SnS2 surface enhance the adsorption energy of LA and reduce the energy barrier of the rate-determining step in the dehydrogenation oxidation process. This work demonstrates that the strategic placement of single atoms on different components of an S-scheme heterojunction can synergistically enhance both the reduction and oxidation half-reactions, offering profound insights for the rational design of high-performance single-atom-loaded S-scheme photocatalytic systems for cooperative H2 production and value-added chemical synthesis.
Manganese-based catalysts offer high 4e− ORR selectivity and low cost, while they suffer from insufficient intrinsic activity. Dual-atom catalysts with rational coordination engineering provide a feasible strategy to further boost electrocatalytic ORR performance. Herein, we report an impregnation–carbonization approach to construct a phosphorus-regulated asymmetric CoMn dual-atom catalyst (CoMnNPC). Unlike conventional M–N4 configuration, asymmetric CoN2P2-MnN4 dual-atom sites are unambiguously verified and anchored in defective graphitic carbon, which generates mutual electron delocalization and optimizes the adsorption of ORR intermediates. Consequently, in 0.1 M KOH electrolyte, the CoMnNPC catalyst delivers an exceptionally high onset potential of 1.02 VRHE and a half-wave potential of 0.87 VRHE with a low H2O2 production of below 3.5% and a transferred electron number of 3.97, outperforming the commercial Pt/C catalyst. The CoMnNPC catalyst also offers a peak power density of 221 mW cm−2 in Zn-air batteries, and remarkable long-term stability can be achieved in flexible all-solid-state batteries. This work provides a reliable strategy for asymmetric coordination regulation of dual-atom catalysts and a high-performance noble-metal-free material for advanced electrochemical energy conversion devices.
Limited by sluggish kinetics and aggressive protonation, the hydrogen peroxide electro-synthesis via two-electron oxygen reduction in acids confronts diminished Faradaic efficiency and production rates. Here, we design and prepare Co single-atom sites (CoNxOy) at fabricated carbon edges with elaborately configured O-coordination using ball-milling and surface oxidations. Operando experimental analysis and theoretical simulations unveil the tuned electronic structure of the CoNxOy sites, leveraging the adsorption of OOH intermediates. Consequently, the asymmetrical coordination moieties hamper electron/proton transfer and preserve O-O bonds, lowering the energy barrier for H2O2 yield. Therefore, the CoNxOy sites achieve excellent H2O2 selectivity of similar to 97 % and Faraday efficiency of similar to 99 % in acidic electrolyte, overwhelming conventional CoN4 sites. Also, the assembled flow cell delivers stable H2O2 production at a concentration of 10 mmol L-1 for over 120 h, thereby enabling effective decomposition of dyes and antibiotics. This work offers insights to leverage coordination asymmetry of single-atom catalysts for oxygen reduction and related electro-catalysis.
Electrocatalytic reduction of nitrate (NO3-) to ammonia (NH3) emerges as a sustainable approach for both wastewater treatment and NH3 synthesis. Herein, we report a hollow-structured PdCuCo medium-entropy alloy supported on reduced graphene oxide (HPdCuCo/RGO) as an efficient and robust electrocatalyst for nitrate reduction reaction (NO3-RR). A unique proton-mediator boosted tandem electrocatalysis toward NH3 production is established on the HPdCuCo/RGO, where Cu sites promote the NO3--to-NO2- conversion, the Co sites facilitate the NO2--to-NH3 conversion, and the Pd sites serve as proton mediators to further boost the tandem catalysis. As a result, the HPdCuCo/RGO exhibit high performance towards NO3-RR in Ar-saturated 0.5 M K2SO4 electrolyte with 2000 ppm NO3-, achieving a NH3-Faradaic Efficiency of similar to 100 % and a corresponding NH3 yield of 36 mg h(-1) mg(cat.)(-1) at -0.5 V versus reversible hydrogen electrode. This study showcases the significant potential of medium-entropy alloys as efficient catalysts for NO3-RR, motivating further exploration into the hitherto underexplored domain of medium-entropy alloys for NO3-RR.
The electrochemical carbon dioxide reduction reaction (CO 2 RR) provides a green avenue for decarbonizing the conventional chemical industries. Here, a structure–selectivity relationship of catalysts is pivotal for the control of a highly selective and active CO 2 RR pathway. We report the fabrication of an oxygen-substituted C 2 N as metal-free catalyst (O─C 2 N) for electrochemical CO 2 ─to─CO conversion with tunable O microenvironment. Combined spectroscopic analysis reveals a fine tailored N─C─O moiety in O─C 2 N, where C─O─C species (e.g., ring in-plane ether) become the dominant oxygen configurations at higher pyrolysis temperatures. Based on experimental observations, a correlation between the exocyclic O-substituted N─C─O─C moieties and CO selectivity is established, giving clear chemical tools for active structure design. The optimized O─C 2 N electrocatalysts with the dominant appearance of C─O─C moieties exhibit an outstanding 2e − CO 2 RR performance with a CO selectivity up to 94.8%, which can be well maintained in a practical flow-cell reactor with an adjustable syngas feature.
Electrochemical synthesis of H2O2via 2-electron oxygen reduction reaction (2e-ORR) renders sustainable alternative to anthraquinone process. However, extensively developed carbon-based electrocatalysts commonly present vulnerability and decayed selectivity in higher reductive potentials. Here, based on the density functional theory simulations, the 2e-ORR capability of oxygen vacancy-rich NiO with exposed (001) is revealed. The predicted end-on manner of oxygen adsorption on the Ni sites contributes the preservation of OO bonds and prevents the over-reduction of OOH* to H2O, thereby facilitates H2O2 formation. Moreover, the according NiO catalyst is experimentally prepared and decorated with island-like NiSe2, which switches the rate-determining step of ORR from the first to second charge transfer with lowered Tafel slope. Consequently, the developed NiO-NiSe2 catalysts achieve excellent Faraday efficiency of >95 % within a wide electrochemical window (0-0.6 VRHE) and deliver stable H2O2 yield of ∼1.2 mol gcat-1 h-1 for over 50 h, overwhelming most transition metal compounds. Meanwhile, practical pulp bleaching is also enabled by real-time production of H2O2 from NiO-NiSe2-based flow cells. This work offers new insights into the design of non-carbon catalysts towards 2e-ORR, deepening the understanding of transition metal compounds in electrocatalysis.
Modulating electronic asymmetry of transition metal (TM) sites attributes to switching their spin state and regulating bonding to oxygen-containing intermediates, thereby facilitating their performance for oxygen reduction reaction (ORR). Herein, we engineer the local coordination structure of the Cu-Co dual-atomic site by integrating phosphorous. The constructed CuCoNPC therefore possesses asymmetric active sites (CoN3-CuN3P), leading to a high spin-state of reactive Co sites. The accordingly tuned dyz orbital occupation consequently triggers the rate-determining step of ORR switching from first (*O2 ->*OOH) to the last protonation (*OH -> H2O). As a result, the CuCoNPC exhibits exceptional ORR activity, with jk of 54 mA cm- 2 at 0.75 VRHE and half- wave potential (E1/2) of 0.86 VRHE, overwhelming that of Pt in alkaline electrolyte. Meanwhile, it also displays a Pt-comparable onset (0.82 VRHE) and E1/2 (0.72 VRHE) in acidic media. Finally, the CuCoNPC catalyst superior performance in liquid-form (Pmax = 194 mW cm- 2) and all-solid-state flexible (OCP = 1.51 V) zinc-air batteries. This work provides valuable guidance in developing active TM-based ORR catalysts via tuning electronic asymmetry.
Mimicking artificial photosynthesis utilizing solar energy for the production of high-value chemicals is a sustainable strategy to tackle the fossil fuel-based energy crisis and mitigate the greenhouse effect. In this study, we developed a two-dimensional (2D) graphene oxide (GO)–diketopyrrolopyrrole (DPP) film photocatalyst. GO nanosheets facilitate the uniform dispersion of DPP nanoparticles (~5 nm) while simultaneously constructing an efficient charge transport network to mitigate carrier recombination. Under visible-light irradiation in an aqueous solution without sacrificial agents, the optimized GO–DPP50 film catalyst exhibited exceptional performance, achieving a CO production rate of 32.62 μmol·g⁻1·h⁻1 with nearly 100% selectivity. This represents 2.77-fold and 3.28-fold enhancements over pristine GO (8.65 μmol·g−1·h−1) and bare DPP (7.62 μmol·g−1·h−1), respectively. Mechanistic analysis reveals a synergistic mechanism. The 2D GO framework not only serves as a high-surface-area substrate for DPP anchoring, but also substantially suppresses charge recombination through rapid electron transport channels. Concurrently, the uniformly distributed DPP nanoparticles improve visible-light absorption efficiency and facilitate effective photogenerated carrier excitation. This work establishes a novel paradigm for the synergistic integration of 2D nanomaterials with organic semiconductors, providing critical design principles for developing high-performance film-based photocatalysts and selectivity control in CO2 reduction applications.
Electrochemical cathodic reductions offer promising approaches for the green synthesis of value-added chemicals, including hydrogen peroxide (H2O2) and ammonia (NH3). Compared with traditional processes, the decentralized electro-synthesis enables on-site production with minimal carbon footprint. In these systems, cathodic catalysts critically govern the overall activity and selectivity of these multi-step reactions. Among the various reported catalysts, carbon-based metal-free electrocatalysts (C-MFECs) have attracted extensive attention, owing to their high conductivity, structural tunability, chemical stability, and eco-friendliness. Given the shared principles in material design and synthesis, this review systematically summarizes recent advances in C-MFECs for H2O2 and NH3 electro-synthesis via oxygen, nitrogen, and nitrate reduction reactions. Special focus is placed on the design strategies for C-MFECs, demonstrating universal understandings of non-metal doping and defect construction in these important reactions. In addition, innovations in electrode architecture and reactor configuration are highlighted to address challenges in achieving high current densities and efficient product separation. Finally, major challenges and perspectives specific to C-MFECs in oxygen, nitrogen, and nitrate electroreductions are highlighted to inform future advances in H2O2 and NH3 electro-synthesis.
Nanosilver is highly competitive catalyst for efficiently electrochemical CO 2 reduction reaction (CO 2 RR), but practical application under large current densities is limited by the high energy barrier for the *COOH formation and the intensified hydrogen evolution reaction (HER). In this study, we reported a strategy of interfacial regulation of surface-modified Ag aerogels (Ag AGs) for high -performance CO 2 RR. The 5-mercapto-1-methyltetrazole (MMT)-modified Ag AGs (MMT@Ag AGs) in H -type cell added with cetyltrimethylammonium bromide (CTAB), achieved CO Faraday efficiency (FE CO ) greater than 95 % in a wide potential window of -0.5 V to -1.2 V vs. RHE, along with the maximum Energy Efficiency (EE CO ) of 73.74 % at -0.5 V vs. RHE. In flow cell, the combination of MMT@Ag AGs + CTAB could deliver an excellent FE CO of 98.5 % under industrial current density of 300 mA cm - 2 and 40 h stability at 100 mA cm - 2 . Density Functional Theory (DFT) calculations illustrated that the *COOH formation energy on Ag AGs was decreased and the adsorption of *COOH was stabilized after modified with MMT. The adsorption arrangement of CTAB on the electrode surface depressed the side reaction of HER. Furthermore, MMT@Ag AGs catalyst exhibited FE CO of 98.73 % and peak power density of 2.11 mW cm - 2 in a customized Zn-CO 2 rechargeable battery, realizing carbon fixation coupling with energy storage technologies.
Metal-free carbon-based materials are one of the most promising electrocatalysts toward 2-electron oxygen reduction reaction (2e-ORR) for on-site production of hydrogen peroxide (H2O2), which however suffer from uncontrollable carbonizations and inferior 2e-ORR selectivity. To this end, a polydopamine (PDA)-modified carbon catalyst with a dipole-dipole enhancement is developed via a calcination-free method. The H2O2 yield rate outstandingly reaches 1.8 mol g(cat)(-1) h(-1) with high faradaic efficiency of above 95% under a wide potential range of 0.4-0.7 V-RHE, overwhelming most of carbon electrocatalysts. Meanwhile, within a lab-made flow cell, the synthesized ORR electrode features an exceptional stability for over 250 h, achieved a pure H2O2 production efficacy of 306 g kWh(-1). By virtue of its industrial-level capabilities, the established flow cell manages to perform a rapid pulp bleaching within 30 min. The superior performance and enhanced selectivity of 2e-ORR is experimentally revealed and attributed to the electronic reconfiguration on defective carbon sites induced by non-covalent dipole-dipole influence between PDA and carbon, thereby prohibiting the cleavage of O-O in OOH intermediates. This proposed strategy of dipole-dipole effects is universally applicable over 1D carbon nanotubes and 2D graphene, providing a practical route to design 2e-ORR catalysts.
Electrochemical oxygen reduction reaction via the two-electron pathway (2e-ORR) is becoming a promising and sustainable approach to producing hydrogen peroxide (H2O2) without significant carbon footprints. To achieve better performance, most of the recent progress and investigations have focused on developing novel carbon-based electrocatalysts. Nevertheless, the sophisticated preparations, decreased selectivity and undefined active sites of carbon-based catalysts have been generally acknowledged and criticized. To this end, transition metal oxides and chalcogenides have increasingly emerged for 2e-ORR, due to their catalytic stability and tunable microstructure. Here, the development of metal oxides and chalcogenides for O2-to-H2O2 conversion is prospectively reviewed. By summarizing previous theoretical and experimental efforts, their diversity and outstanding catalytic activity are firstly provided. Meanwhile, the topological and chemical factors influencing 2e-ORR selectivity of the metal oxides/chalcogenides are systematically elucidated, including morphology, phase structures, doping and defects engineering. Thus, emphasizing the influence on the binding of ORR intermediates, the active sites and the underlying mechanism is highlighted. Finally, future opportunities and challenges in designing metal oxides/chalcogenides-based catalysts for H2O2 electro-synthesis are outlined. The present review provides insights and fundamentals of metal oxides/chalcogenides as 2e-ORR catalysts, promoting their practical application in the energy-related industry.
In the realm of polymer-based 3D photo printing, challenges arise from the side effects, notably the persistent presence of photocatalyst residues and metal contamination. These impurities pose significant risks in various applications, including electronics, biological tissues, and medical implants. At the same time, spatial-/time-/light-controlled 3D photo printing has been hindered by low-efficiency polymerization concerning both initiation and monomer conversion. To address these criti-cal issues, a pioneering concept, “degradation-inhibited quench,” is introduced and implemented within photopolymeriza-tion to solve the problems mentioned above. This innovative approach aims to produce pure polymers via higher-efficiency Atom Transfer Radical Polymerization (ATRP) with a unique class of diketopyrrolopyrrole (DPP) derivatives as organo-photocatalysts at an extremely low concentration (as low as 50ppm). Through this approach, pure polymers with ultra-high molecular weight (UHMW) have been successfully synthesized. For instance, poly(methyl methacrylate) (PMMA) achieved a monomer conversion of > 50%, a molecular weight of 2.1 million, and a dispersity of 1.38 after 12 h additional dark reaction. Notably, this novel photopolymerization method demonstrates applicability across a broad spectrum of monomers, with or without solvents, including acrylate, acrylic, styrene, and acrylonitrile. Mechanism insights revealed that the production of UHMW PMMA stemmed from the degradation of intermediate complex DPP•+/Br-, which originated from the photo initiation. This degradation inhibited the oxidative quenching of active propagating chain radicals, thereby significantly extending their lifespan. This groundbreaking concept embraces the potential for further development of highly effective organo-photocatalysts and reactive systems specifically tailored for 3D photopolymerization. Moreover, this novel spatial-/time-/light-controlled polymerization approach does not require any additional purification, offering energy and cost-saving manufacturing technology.
For efficient removal of the antibiotic-resistance bacteria and antibiotic-resistance genes, zirconium-doped zinc-aluminum layered double hydroxide/graphene oxide (Zn-Al-Zr LDHs/GO) nanocomposite has been developed. The Zn-Al-Zr LDHs/GO shows outstanding photocatalytic sterilization, inactivating kanamycin-resistance E. coli (6.53 log10 CFU/mL) under the full-wavelength light irradiation within 50minutes. Owing to the 1O2 formation, it greatly disrupts the respiratory chain of the kanamycin-resistance E. coli, thereby leading to a declined yield of adenosine triphosphate, down-regulated expressions of the DNA ligase and polymerase proteins, as well as completely inhibited expressions of the DNA repair proteins. Meanwhile, the strong adsorption capability of the Zn-Al-Zr LDHs/GO towards phosphorus endows it with special nano-confinement effects for ARGs. It results in significantly enriched local concentration of the kanamycin-resistance genes on the Zn-Al-Zr LDHs/GO, consequently enhanced removal ability towards the kanamycin-resistance genes (4.70 log10 copies/mL in 3hours). This work provides a new strategy for effectively removing the ARB and ARGs.
