Summary: In this study, researchers propose a versatile strategy that utilizes carbon vacancies to regulate the electronic configuration of antimony (Sb) atoms on carbon nitrides (C3N4), significantly enhancing the photocatalytic production of H2O2. The H2O2 evolution rate of Sb single-atom on carbon vacancy-rich C3N4 is 10.9 times higher than C3N4 alone. The strong electronic interaction between Sb atoms and carbon vacancy-rich C3N4 is capable of maintaining the electron-rich state of Sb atoms, facilitating efficient electron transfer, and enhancing the formation of *OOH intermediates.

Summary: In this study, a simple strategy of engineering Pt single atoms on a 2D hydrazone-based covalent organic framework (TCOF) was proposed to promote H-2 production coupled with selective oxidation of benzylamine. The optimised TCOF-Pt SA photocatalyst exhibited superior performance compared to TCOF and TCOF-supported Pt nanoparticle catalysts. The atomically dispersed Pt on the TCOF support induced local polarization and improved the dielectric constant, resulting in the promotion of exciton dissociation and the acceleration of charge carrier separation and transport.

Summary: ZrO2 can photoreduce 13CO2 to 13C-products under ultraviolet-visible light, with minimal influence from adventitious carbon. The dual-site reaction pathway from CO2 to CO using monoclinic ZrO2 was theoretically elucidated, followed by hydrogenation steps to methane over Ni nanoparticles. Oxygen vacancy (VO center dot center dot) played crucial roles in CO2 adsorption and hydroxycarbonyl species dissociation on ZrO2(111) surface. The rate-limiting step was VO center dot center dot site regeneration, with an activation energy of 2.6 eV, but compensated by CO2 adsorption energy. The transfer of COH and/or CO species from ZrO2 to Ni in a concerted mechanism reduced the apparent Eact value to methane to 0.67 eV.

Summary: Regulating the energy barrier of *COOH is crucial for the rate determining step in the photocatalytic reduction of CO2 to produce CO gas. In this study, an appropriate Zn vacancy on ZnIn2S4 was synthesized to enhance the photocatalytic CO2 reduction capacity (CO: 5.63 mmol g(-1) h(-1)) and selectivity (CO: 97.9%). Different sulfhydryl groups were used to regulate the formation of Zn vacancies in ZnIn2S4, leading to the generation of unsaturated sulfur coordination state adjacent to the Zn vacancy with fewer electrons compared to ZnIn2S4 without Zn vacancy. Experimental analysis and theoretical calculations demonstrated that the appropriate Zn vacancy shifted the Gibbs free energy of *COOH from endothermic to exothermic during the photoreduction of CO2. This work provides an engineering method to optimize cation vacancies and improve the efficiency of photocatalytic CO2 reduction by adjusting the energy barrier of intermediates.

Summary: This study demonstrates that Ru nanoparticles supported on natural halloysite nanotubes can enhance the photothermal catalytic activity and selectivity of CO2 methanation under continuous flow conditions. The optimized catalyst exhibits a photothermal catalytic performance of 1704 mmolCH(4) g(cat)(-1) h(-1) with 93% CH4 selectivity and 68% CO2 conversion, surpassing other Ru-based catalysts in photothermal CO2 reduction. The excellent catalytic performance is attributed to the unique mesoporous tubular structure, efficient light-to-heat conversion, and interfacial interactions between halloysite nanotubes and Ru. This method of utilizing natural minerals as support provides a convenient approach for the rational design of abundant and low-cost catalysts for efficient photothermal catalytic CO2 reduction.

Summary: Hydrogen dopants and oxygen vacancies are important in BiVO4 photoanodes, but the impact of hydrogenation on charge transport, particularly electron small polaron formation, is not well understood. This study demonstrates that mild hydrogenation of nanoporous BiVO4 reduces the charge transport barrier, as shown by thermally activating photocurrent responses. The hydrogen atoms occupy oxygen vacancies, reducing the activation energy and facilitating electron small polaron transport. A BiVO4 photoanode with NiFeOx cocatalyst achieves an applied-bias photon-to-current efficiency of 1.91% at 0.58 V vs RHE. This study expands the understanding of hydrogen doping beyond conventional donor density/surface chemisorption mediations to include small polaron hopping.

Summary: This study demonstrates the great potential of using highly stable and active Ni-based photocatalysts for photocatalytic overall water splitting (POWS). Ni nanoparticles encapsulated in a nitrogen-doped ultrathin graphene layer were found to be an active, stable, and low-cost cocatalyst for POWS. The H-2 evolution rate over this cocatalyst was significantly higher than that of typical Pt cocatalyst, and the oxidation of Ni during the reaction was effectively suppressed through N-doped graphene coating. In addition to improving charge carrier dynamics, the introduction of N reduced the apparent activation energy of POWS.

Summary: ZrO2 can photoreduce 13CO2 to 13C-product(s) under UV-visible light with minimal impact from adventitious carbon. The dual-site reaction pathway from CO2 to CO is explained by monoclinic ZrO2, followed by hydrogenation to methane via Ni nanoparticles. The oxygen vacancy (VO center dot center dot) plays a crucial role in CO2 adsorption and occupation by O and/or hydroxy groups on the ZrO2(111) surface. The regeneration of the VO center dot center dot site is the rate-limiting step with an activation energy of 2.6 eV, but the CO2 adsorption compensates for the desorption energy of water. Transfer of COH and/or CO species from ZrO2 to Ni is energetically favorable with an apparent Eact value of 0.67 eV for the conversion of hydroxycarbonyl species to methane.
