Efficient photoelectrochemical hydrogen production over CuInS2 photocathodes modified with amorphous Ni-MoSx operating in a neutral electrolyte

Author affiliations

Abstract

CuInS2 photocathodes were prepared and surface modified for photoelectrochemical hydrogen production in a neutral potassium phosphate electrolyte. This work represents the first-ever demonstration that Ni-MoSx provides better catalytic activity than Pt as a hydrogen evolution reaction catalyst on the CuInS2 surface, likely due to the junction formed between the CuInS2 and Ni-MoSx layers.
