Abstract ：
Employing photocatalytic technology to transform CO2 into valuable fuels is considered a promising solution for addressing the exacerbated greenhouse effect and energy crisis. The development of photocatalysts featuring superior charge separation efficiency is pivotal for the widespread implementation of photocatalytic CO2 reduction technologies. Herein, zero-dimensional (0D) NixP nanoparticles are anchored onto two-dimensional (2D) LaTiO2N nanosheets by a photo-deposition method, and a NixP/LaTiO2N Schottky junction composite with excellent photocatalytic CO2 reduction performance is constructed. The optimal NixP/LaTiO2N composite achieves CO and CH4 yields of 9.39 and 4.15 mu mol g-1 h-1, respectively, with the utilized photoelectron number (UPN) reaching 51.98 mu mol g-1, which is approximately 9.7 times higher than that of LaTiO2N alone. The improved photocatalytic performance of the composites can be attributed to the formation of Schottky junctions, which effectively suppress the recombination of photogenerated carriers. This study provides a new idea for the development of 0D/2D Schottky junction photocatalysts.

Abstract ：
The photocatalytic conversion of CO2 into hydrocarbon fuel holds immense potential for achieving a carbon closed loop and carbon neutrality. Developing efficient photocatalysts plays a pivotal role in enabling the widespread application of photocatalytic CO2 reduction on a large scale. Herein, a novel S-scheme MnWO4/LaTiO2N heterojunction composite is successfully synthesized by a hydrothermal method. This composite catalyst demonstrates excellent photocatalytic activity in the reduction of CO2 to CO and CH4 using water molecules as electron donors under visible light irradiation, and the optimized 30% MnWO4/LaTiO2N composite displays significantly enhanced CO and CH4 yields of 3.94 and 0.81 μmol g-1 h-1, respectively, and the corresponding utilized photoelectron number reaches 14.7 μmol g-1 h-1, which is approximately 7.7 and 12.9 times that of LaTiO2N and MnWO4. The enhancement in photocatalytic activity of the composites can be ascribed to the construction of an S-scheme heterojunction, which exhibits improved charge transfer dynamics, retains the strongest redox capacity, and effectively suppresses back reactions. In situ Fourier-transform infrared imaging provides evidence, to a certain extent, for the existence of a temporal gradient order in the generation of multiple products during the photocatalytic reduction of CO2. © 2024 American Chemical Society.

Abstract ：
Solar-powered photocatalytic water splitting for hydrogen evolution presents a promising solution to the energy crisis and contemporary environmental challenges. Herein, a Z-scheme ZnS/LaTiO2N heterojunction composite, incorporating zinc vacancies, has been successfully synthesized to enable photocatalytic hydrogen evolution under visible-light illumination. The optimized ZnS(VZn)/LaTiO2N composite demonstrates a hydrogen evolution activity 13 times higher than that of individual ZnS(VZn). The heterojunction between ZnS and LaTiO2N, in conjunction with zinc vacancies, expands the photoresponse spectrum and facilitates the spatial separation and transfer of photogenerated carriers. Consequently, this synergy significantly enhances the performance of photocatalytic hydrogen evolution. The collaborative action of the Z-scheme heterojunction and zinc vacancies paves the way for innovative approaches in designing future high-efficiency photocatalysts.

Abstract ：
Cu2O is one of the most promising photocatalysts for visible light driven CO2 conversion, but its practical application in artificial photosynthesis is challenged to severe photocorrosion. Herein, a Cu2O/LaTiO2N composite is successfully synthesized by loading Cu2O on LaTiO2N through an ascorbic acid reduction method, which significantly improves the stability and activity of Cu2O for visible light driven photocat-alytic CO2 conversion, and shows higher photocatalytic performance than most Cu2O-based photocata-lysts reported. The superior photocatalytic performance is attributed to the formation of type-II heterojunction between Cu2O and LaTiO2N, which facilitates the separation and transfer of photogener-ated electrons and holes. This work provides an effective strategy for the construction of stable and effi-cient Cu2O-based photocatalysts. (c) 2022 Elsevier Inc. All rights reserved.

Abstract ：
Coupling hydrogen production with selective organic synthesis in one cooperative manner offers a novel strategy for green synthesis by virtue of the photogenerated carriers. Herein, a dual-functional photocatalyst of CoSx/Cd0.7Zn0.3S without noble metals is reported for efficient selective benzaldehyde (BAD) synthesis coupled with H-2 production. The CoSx/Cd0.7Zn0.3S composite showed a higher photocatalytic performance than Cd0.7Zn0.3S and 1 wt% Pt/Cd0.7Zn0.3S, which was attributed to the loaded CoSx, as the cocatalyst, which could accumulate the photogenerated electrons from Cd0.7Zn0.3S, promote the separation of photogenerated charge carriers, and reduce the overpotential of hydrogen production. This study provides a new strategy for the design and synthesis of low-cost, high-efficiency composite materials for photocatalytic efficient selective benzaldehyde (BAD) synthesis coupled with H-2 production.

Abstract ：
Using solar-powered photocatalytic technology to convert CO2 to high value-added chemical products is a hopeful strategy to solve the energy and environmental problems of modern society. Herein, a direct Z-scheme InVO4/La2Ti2O7 photocatalyst is successfully synthesized, achieving efficient and selective CO2 re-duction to CO with nearly 100 % CO selectivity, and the CO yield is 4.2 and 3.3 times that of individual La2Ti2O7 and InVO4, respectively. The significantly enhanced photocatalytic performance is owing to the formation of Z-scheme charge transfer mechanism, fostering the spatial separation and transfer of pho-togenerated carriers. This work provides new perspectives for the rational design of La2Ti2O7-based pho-tocatalytic materials toward efficient and selective CO2 reduction to CO. (c) 2022 Elsevier B.V. All rights reserved.
