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-MoS_x 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-MoS_x layers.

在中性电解质中操作的无定形Ni-MoSx修饰的CuInS2光电阴极上的高效光电化学制氢

制备了CuInS ₂光电阴极并对其进行了表面改性，以在中性磷酸钾电解质中进行光电化学制氢。这项工作代表了有史以来的首次证明，Ni-MoS _x在CuInS ₂表面上提供了比Pt更好的催化活性，作为氢释放反应催化剂，这可能是由于CuInS ₂和Ni-MoS _x层之间形成的结。
