Zn3 (VO4) 2-Ni (OH) 2 electro-catalytic complete water splitting material as well as preparation method and application thereof

The invention belongs to the technical field of electro-catalysis materials, and particularly relates to a Zn3 (VO4) 2-Ni (OH) 2 electro-catalysis full water splitting material and a preparation method and application thereof. According to the Zn3 (VO4) 2-Ni (OH) 2 electro-catalysis full water splitting material, a Zn3 (VO4) 2 nanosheet is attached to a large Ni (OH) 2 sheet. The Zn < 3 > (VO4) 2 sheet attached Ni (OH) < 2 > nanosheets are prepared by combining a precipitation method and a hydrothermal method, and the Zn < 3 > (VO4) 2-Ni (OH) < 2 > electrocatalytic material prepared by the method is excellent in complete water splitting performance and good in cycle performance, can be continuously applied for a long time, and does not cause secondary pollution to the environment in the application process. The preparation method disclosed by the invention is low in raw material cost, simple and convenient to operate and environment-friendly and has the potential of large-scale production. 本发明属于电催化材料技术领域，尤其涉及
