Abstract Semiconductor hybrid structures containing multiple components have been considered an ideal photocatalyst design to generate long‐lived charge‐separated states. The reaction activity is highly susceptible the catalyst component and morphology, particularly for reactions requiring high activation energies, such as a CO 2 reduction (CO RR). In this study, we selected g‐C 3 N 4 Cu O photocatalytic having bandgaps suitable RR. Our approach involved establishing robust electric junctions between these domains by direct growth of on via polyol process. resulting /Cu was employed photocatalysts in aqueous medium without hole acceptors. exhibited notable activities (94 μmol g cat −1 h ) CH production (218 ), maintaining stability over 6 h. inherent synergy O, facilitated formation conductive junctions, enabled efficient electron transfer promote These findings ensured importance interfaces unlocking superior RR performance.

Abstract Currently, the concentration of carbon dioxide (CO 2 ) has exceeded 400 ppm in atmosphere. Thus, there is an urgent need to explore CO reduction and utilization technologies. Photocatalytic technology can convert valuable hydrocarbons (CH 4 , CH 3 OH, C H 5 etc.), realizing conversion solar energy chemical as well solving problems fossil fuel shortage global warming. Graphitic nitride (g‐C N ), a two‐dimensional nonmetallic semiconductor material, shows great potential field photoreduction due its moderate bandgap, easy synthesis method, low cost, visible light response properties. This review elaborates research progress g‐C ‐based photocatalysts for photocatalytic reduction. The modification strategies (e.g., morphology engineering, elemental doping, crystallinity modulation, cocatalyst modification, constructing heterojunction) application have been discussed detail. Finally, challenges development prospects materials are presented.
