The invention discloses a preparation method of a bifunctional Co 2-x Ni x O 2 nanomaterial for electrocatalysis of total water splitting. The method comprises the steps of preparing hydroxide by co-precipitation method and calcining to prepare Co 2-x Ni x O 2. The steps of preparing Co 2-x Ni x O 2 modified working electrode materials by nanomaterials and dispersion method are completed. Catalysis, including catalytic oxygen evolution reaction and catalytic hydrogen evolution reaction. Moreover, it has the advantages of low cost, good stability, low resistivity, simple preparation method and the like. The synthesized Co 2-x Ni x O 2 nano-electrode materials are used to replace commercial nano-electrode materials such as Pt/c, RuO 2 , IrO 2 , etc., in order to solve the problems of high price and low efficiency of the total water splitting electrode, and provide a high-efficiency, A method to facilitate the promotion and application. |
