Summary: The transformation of biomass into chemicals and fuels is a long-term goal in both science and industry, but high cost is a major obstacle to industrialization. Therefore, the development of catalysts with high activity and low cost is crucial. The use of earth-abundant 3d-transition-metals in catalysis has seen increasing achievement in the past two decades due to their low cost, high efficiency, and excellent stability.

Summary: Using few-layered nanosheet-assembled hierarchical BiOBr nanotubes with rich oxygen vacancies (OVs) as efficient photocatalysts, the simultaneous study of charge transfer and energy transfer steps in a photoexcitation process is proposed. The optimized BiOBr photocatalyst shows improved charge carrier separation and transfer, as well as enhanced exciton generation, resulting in high efficiency for photocatalytic CO2 reduction. The dominant reactive oxygen species, singlet oxygen (O-1(2)), is identified for the first time as originating from an energy transfer process, while the minor effect of superoxide anion radical (O-center dot(2)-) is observed in the photocatalytic aerobic oxidation of sulfides.

Summary: Controllable product selectivity in CO2 hydrogenation is achieved by light-induced switching of reaction pathways over Co decorated Pt@UiO-66-NH2. With light irradiation, the main product CO is switched to CH3OH via the formate pathway, resulting in a significantly higher space-time yield of CH3OH. Mechanism investigation reveals that excited UiO-66-NH2 can transfer electrons to Pt nanoparticles and Co sites, promoting the CO2-to-*HCOO conversion and suppressing the reverse water gas shift (RWGS) pathway.
