Abstract In the field of photocatalysis, most of the photocatalysts are semiconductors. Recent years, there have been many photocatalytic systems related to non-semiconductor catalysts. In this paper, a photocatalytic hydrogen evolution system of hexagonal Ni(OH)2 derived from CuNi bimetal is obtained by classical hydrothermal method. The derived hexagonal Ni(OH)2 can promote the separation of photogenerated electron-hole pairs and greatly improve the effect of photocatalytic hydrogen evolution. The electron-hole pair comes from the surface plasmon resonance (SPR) effect of Cu from CuNi composite. It is worth noting that photoluminescence spectra and photoelectrochemical experiments have confirmed that the CuNi-5 complex can effectively improve space charge separation. The results of linear scanning voltammetry show that the material has high current response characteristics. This system gives a practical solution for planning and synthesizing non-semiconductor catalysts with high photocatalytic activity.
