Copper vanadate electrode material, preparation method and application of copper vanadate electrode material in photoelectrocatalytic hydrogen production

The invention belongs to the technical field of advanced materials, and relates to a copper vanadate electrode material, a preparation method and application of the copper vanadate electrode material in photoelectrocatalytic hydrogen production. The preparation method comprises the following steps: mixing a copper nitrate solution and a bis (acetylacetone) oxovanadium (VOC (AcAc) 2) solution to prepare a precursor solution, performing spray pyrolysis on the precursor solution to obtain a precursor film on the surface of a substrate, and performing annealing treatment on the precursor film in an air atmosphere, thereby obtaining the copper-based composite material. The alpha-CuV2O6 prepared by the method does not contain CuO, V2O5 and other copper vanadate phases, is relatively high in purity, has relatively high PEC efficiency, and can be used as an electrode material for solar water decomposition. 本发明属于先进材料技术领域，涉及钒酸铜电极材料及制备方法与其在光电催化制氢中的应用。将硝酸铜溶液和双(乙酰丙酮)氧钒(VO(AcAc)2)溶液混合制成前驱体溶液，将前驱体溶液进行喷雾热解在基板表面获得前驱体膜，将前驱体膜在空
