The invention discloses a preparation method of a nickel oxide-cobaltosic oxide (NiO/Co3O4) composite electrode material based on foamed nickel growth. The process comprises the following steps of: firstly, preparing a precursor of nickel oxide through a hydrothermal method by taking nickel nitrate and urea as raw materials, ammonium fluoride as a morphology control agent and foamed nickel as a substrate, carrying out low-temperature annealing on the precursor in air to obtain pure NiO, and then taking the nickel oxide as a substrate material, adding a cobalt acetate solution and ammonia water, and carrying out a second-step hydrothermal reaction to obtain the NiO/Co3O4 two-phase composite electrocatalyst material growing on a foamed nickel substrate.
