摘要

To facilitate the photocatalytic H2 production capacity of the g-C3N4, we anchored the amorphous cobalt nickel sulfide onto g-C3N4 as bimetallic cocatalyst by a facile photoinduced deposition process, recorded as CoNiSx/g-C3N4 (CNGN). The photocatalytic H2 generation capacity of CNGN was up to 286.1 µmol/h, around 7.1 times that of bare g-C3N4. The enhancement in photocatalysis of CNGN could be ascribed to the harvesting of photogenerated electrons of g-C3N4 nanosheets by bimetallic co-catalyst, resulting in the effective photogenerated charges separation and promoting the photocatalytic H2 production capacity of the g-C3N4 nanosheets.
