Promotion of the excited electron transfer over Ni- and Co -sulfide co-doped g-C3N4 photocatalyst (g-C3N4/NixCo1−xS2) for hydrogen Production under visible light irradiation

Abstract A Ni- and Co- sulfide co-doped g-C3N4 photocatalyst (g-C3N4/NixCo1−xS2) was prepared by hydrothermal method and this photocatalyst, namely, g-C3N4/NixCo1−xS2 shown excellent photocatalytic properties due to the special structure of Ni-Co-S with boundary different exposure to active site of...
