Photocatalytic CO2 Reduction Over BiOX on Needle Coke–Derived Graphene Composites
Carbon and Hydrogen, EarlyView.By in situ growing BiOX on needle coke–derived graphene to construct a composite photocatalyst, interfacial charge transfer is effectively enhanced. The optimized BiOBr‐25%NCG achieves a CO production rate of 46.32 μmol·g−1·h−1 from photocatalytic CO2 reduction without sacrificial agents.
