Synergistic effect between sulfur vacancies and S-scheme heterojunctions in WO/V-ZnInS for enhanced photocatalytic CO reduction in HO vapor.

Converting CO into CO, CH, and other hydrocarbons using solar energy presents a viable approach for addressing energy shortages. In this study, photocatalysts with S-deficient WO/ZnInS (WO/V-ZIS) S-scheme heterojunctions have been successfully synthesized. Under UV-vis light irradiation, 20 %WO/V-ZIS demonstrated significantly improved CO reduction activity and CH selectivity.

Strain-Induced Self-Assembly at Interface of Two-Dimensional Heterostructures Boosts CO Reduction to Methanol by HO.

CO conversion with pure HO into CHOH and O driven by solar energy can supply fuels and life-essential substances for extraterrestrial exploration. However, the effective production of CHOH is significantly challenging. Here we report an organozinc complex/MoS heterostructure linked by well-defined zinc-sulfur covalent bonds derived by the structural deformation and intensive coupling of d(Zn)-p(S) orbitals at the interface, resulting in distinctive charge transfer behaviors and excellent redox capabilities as revealed by experimental characterizations and first-principle calculations.

Unraveling Synergistic Effect of Defects and Piezoelectric Field in Breakthrough Piezo-Photocatalytic N Reduction.

Piezo-photocatalysis is a frontier technology for converting mechanical and solar energies into crucial chemical substances and has emerged as a promising and sustainable strategy for N fixation. Here, for the first time, defects and piezoelectric field are synergized to achieve unprecedented piezo-photocatalytic nitrogen reduction reaction (NRR) activity and their collaborative catalytic mechanism is unraveled over BaTiO with tunable oxygen vacancies (OVs). The introduced OVs change the local dipole state to strengthen the piezoelectric polarization of BaTiO , resulting in a more efficient separation of photogenerated carrier.

Atomically Dispersed Electron Traps in Cu Doped BiOBr Boosting CO Reduction to Methanol by Pure H O.

Overall photocatalytic conversion of CO and pure H O driven by solar irradiation into methanol provides a sustainable approach for extraterrestrial synthesis. However, few photocatalysts exhibit efficient production of CH OH. Here, BiOBr nanosheets supporting atomic Cu catalysts for CO reduction are reported.
