Layered double hydroxides (LDH) are regarded as an outstanding adsorbent with the ability to capture CO2. Nevertheless, the stacking and curling of CoAl-LDH significantly impact the CO2 adsorption performance. In this study, CoAl-LDH were synthesized on a rigid palygorskite (Pal) framework to form a hierarchical CoAl-LDH/Pal composite, which effectively reduced the original particle size of CoAl-LDH and addressed the drawbacks. Subsequently, polyethylene imine (PEI) was impregnated onto the surface of CoAl-LDH/Pal to fabricate PEI/ CoAl-LDH/Pal adsorbent, further improving the CO2 capture performance. Finally, the mechanism of CO2 adsorption was also elaborated. The PEI/CoAl-LDH/Pal demonstrated a higher equilibrium adsorption capacity and a longer breakthrough time for CO2 capture, with the adsorption capacity reaching 158.8 mg/g and increasing by 8 times compared to that of CoAl-LDH/Pal. Herein, CO2 was adsorbed on the surface of PEI/CoAlLDH/Pal in the forms of bicarbonate and amino carboxylate. Additionally, PEI/CoAl-LDH/Pal exhibited excellent regeneration performance and maintained the adsorption capacity over 9 cycles, which is anticipated to be a promising candidate for CO2 capture.

Photothermal catalytic conversion of CO2 and H2O to solar fuels has great potential in industry but remains challenge using full solar spectrum. Herein, plasmonic Sn:In2O3/H-ATP(acid modified attapulgite) heterojunction was prepared by coprecipitation coupled with microwave hydrothermal method. The localized surface plasmon resonance (LSPR) effect of In2O3 triggered by doping with Sn2+ broadened the absorption range from visible to mid-infrared light and released high-energy hot electrons by providing heat simultaneously. Results revealed that the Sn:In2O3/H-ATP demonstrated remarkable CO2 photoreduction property with a CO yield rate of 17.9 & mu;mol g-1 h-1 and 84 % selectivity under solar light irradiation. The apparent quantum yields (AQE) achieved 1.7 % at 420 nm. The H-ATP not only immobilized Sn:In2O3 to trap CO2 molecules attributed to its large specific area and adequate active sites, but also acted as a semiconductor to build S-scheme heterostructure with Sn:In2O3, which provided an effective way to capture and transform CO2. In addition, in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was used to explore the photocatalytic reduction CO2

Photo-driven reformation of cellulose biomass is deemed a promising technology to produce value-added chemicals. Herein, the photocatalytic conversion of cellulose to 5-hydroxymethylfurfural (5-HMF) employing a palygorskite (Pal) clay-based composite as a catalyst was reported. Pal modified with phosphoric acid (P-Pal) not only induced the growth of Cu-2(PO4)(OH) nanosheets on its surface with high dispersion effectively enhancing light absorption, but also enabled intimate adsorption of catenulate cellulose in the colloidal solution. The in-situ precipitated Cu-2(PO4)(OH) owned abundant Lewis acid sites and localized surface plasmon resonance (LSPR) effect, which extended the absorbance range to near-infrared (NIR) light and provided a substrate for local thermal activation. Under simulated solar light irradiation, Bronsted acid provided by P-Pal and the formed hydroxyl radicles (center dot OH) synergistically facilitated the cleavage of the beta-1,4-glycosidic bond of cellulose to produce glucose, while the Lewis acid sites directed the selective glucose isomerization to produce 5-HMF. The 20 wt % Cu-2(PO4)(OH)/P-Pal exhibited the highest 5-HMF selectivity of 72% along with remarkable reusability, and the yield of 5-HMF reached 53 mg/L even under NIR irradiation, benefiting from the immobilization and acid sites of the Pal clay.

An efficient heterostructure, compactly durian-like mischcrystal TiO2/graphene containing the anatase and rutile phase, was prepared via a seed-induced synthesis. The TiO2 seed crystal on the surface of graphene plays a vital role in the formation of durian-like mischcrystal TiO2/graphene. The scattered rutile-TiO2 nanoparticles interspersed on the crystal planes of anatase-TiO2 tetrahedron. This novel configuration improved the BET specific surface area to 71.28 m2/g and the visible light response range of multiphase TiO2/graphene. The heterostructure and the synergistic effect between the anatase and rutile TiO2 could transfer the electron, leading to suppress the electron-hole recombination. After 3 h irradiation, the desulfurization rate of durian-like mischcrystal TiO2/graphene photocatalyst reached 83.5% for dibenzothiophene.

Developing low cost and efficient strategy to eliminate volatile organic compounds (VOCs) are quite urgent and challenging. Herein, CeO2 nanoparticles co-doped with Yb3+ and Er3+ were immobilized on attapulgite clay (ATP) for photothermal catalytic oxidation of toluene. The CeO2:Yb3+, Er3+/ATP exhibited outstanding catalytic activity with low T90 of 295 degrees C (temperature at 90% degradation), satisfactory stability and highly water resistance. The enhanced photothermal catalytic performance can be attributed to the optimal introduction of Yb3+ and Er3+, which promoted the up-conversion of near-infrared light (NIR) to visible light increasing the light utilization. The defects caused by Yb3+/Er3+ doping facilitated the adsorption of O2, while the active oxygen species generated from the defects and the photoinduced reactive species not only favored the oxidation of toluene in photothermal catalytic process, but also accelerated the reoxidation of reduced catalyst. Notably ATP support provided large specific surface area and abundant adsorption sites for toluene molecules to promote the deep oxidation and hindered the deactivation of catalysts caused by the accumulation of intermediates. In-situ DRIFTS test revealed that the alkoxide and benzoate appeared as the main intermediates, which can be deeply oxidized under light irradiation. Current work provides a new alternative for photothermal catalytic degradation of VOCs. (c) 2022 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Photocatalysis has great potential on converting lignin biomass to value-added chemicals. Herein, dendritic-like CeVO4 in situ grew on the phosphoric acid-activated palygorskite (P-Pal) nanomd surface and 5% incorporation of Gd3+ ions achieved the strongest up-conversion property, which converted near infrared (NIR) light into UV and visible light boosting the absorption range of solar energy. Under optimized 6 h sunlight irradiation, the highest conversion rate of sodium lignosulfonate (SLS) can reach 73.2%, and the vanillin yield can reach 4.5 mg/g(SLS). Gd3+: CeVO4 and P-Pal formed well-defined Z-scheme heterojunction which retained strong redox ability of charge carriers, and center dot O-2(-) acted as the main reactive species for the photocatalytic conversion of SLS to valuable products. Notably, abundant Lewis acid sites and Brunsted acid sites induced by phosphoric acid acted as active sites boosting the cleavage of C-C bonds in SLS. Present work offers an alternative for mineral-based catalysts toward photocatalytic conversion of biomass.

The innovation of cost-effective ammonia synthesis under mild condition to replace traditional HaberBosch process remains a grand challenge. In this work, partial cations in one-dimensional clay palygorskite (Pal) were substituted by Fe ions to achieve lattice reconstruction, followed by in situ precipitation of FeS2 nanoparticles using a microwave hydrothermal method. The band gap of Fe-modified Pal was largely reduced with the perseverance of its original crystal structure. As the Fe content exceeded 20 wt%, excess Fe ions on the surface of Fe-Pal reacted with sulfide ions to form iron sulfide (FeS2), which owned narrow bandgap (1.3 eV) responsive in near infrared (NIR) light. The presence of abundant sulfur vacancies (Sv) as well as Fe species served as nitrogen adsorption and activation center, which promoted the adsorption of N-2 and weakened the N N triple bond. A Z-scheme heterostructure can be formed between Fe-Pal and FeS2 intermediated by Sv, improving the adsorption range of solar light and enhancing the redox potential for N-2 reduction. The optimized 40 wt% Fe-Pal exhibited remarkable N-2 fixation ability in a wide spectrum, providing a new perspective for cost-effective photocatalytic nitrogen fixation. (c) 2021 Elsevier B.V.

Developing photocatalysts with wide spectrum absorption and strong nitrogen activation is critical for nitrogen fixation under mild conditions. Herein, one-dimensional natural clay attapulgite (ATP) supported YF3:Sm3+ were successfully synthesized via microwave hydrothermal method, and the composites were employed as the catalyst for photocatalytic nitrogen fixation under visible-light irradiation. Results indicated that the production of ammonia reached as high as 41.2 mg·L−1 within 3 h when the molar ratio of Sm3+ and the mass fraction of YF3:Sm3+ were optimized. The enhanced fixation performance is mainly due to that the modified ATP fibber with abundant active sites and the doped fluoride with defective vacancy facilitate the adsorption and activation of N2. Furthermore, the upconversion property of YF3:Sm3+ increases the harvesting of visible-light energy, meanwhile the Z-scheme heterostructure built between YF3:Sm3+ and modified ATP inhibits the recombination of charge carriers and retains high redox potentials for N2 reduction.
