In situ loading amorphous CoSx on N-doped g-C3N4 through light assisted synthesis for enhanced photocatalytic hydrogen generation

Loading co-catalysts are an effective strategy to break the confinement of bulk carbon nitride in photocatalysis . Employing this strategy, N-doped g-C 3 N 4 decorated with CoS x was successfully prepared through a photochemical synthesis route. The optimum hydrogen evolution performance of N-CN-CoS x -4 was 1757 μmol g −1  h −1 under visible light irradiation . Superior interfacial carrier transfer properties and improved light absorption of N-CN-CoS x -4 could elucidate its better photocatalytic activity . This research offers a reference for the construction of high-efficiency, stable and low-priced photocatalysts .
