Abstract

The invention provides a preparation method of a ball-flower-like V-doped Ni3S2 / NF self-supporting electrode material. The preparation method comprises the steps of soaking cleaned foam nickel into apolymeric precursor solution containing nickel chloride hexahydrate, vanadium chloride, ammonium fluoride and urea to conduct primary hydrothermal reaction; soaking the reactive foam nickel into an aqueous solution containing thioacetamide and polyvinyl pyrrolidone to conduct secondary hydrothermal reaction to obtain the ball-flower-like V-doped Ni3S2 / NF self-supporting electrode material. The invention further discloses the ball-flower-like V-doped Ni3S2 / NF self-supporting electrode material. The preparation method provided by the invention is simple in operation, and the reaction period is short. The prepared V-doped Ni3S2 is uniform in morphology and has the self-assembly structure, and the electro-catalytic property of the material is effectively improved.
