Nickel-cobalt sulfide compound material as well as preparation method and application thereof

The invention relates to the technical field of electrochemistry, in particular to a nickel-cobalt sulfide compound material and a preparation method and application thereof.The preparation method comprises the following steps that foamed nickel is pretreated in a surfactant aqueous solution, and pretreated foamed nickel is obtained; taking the pretreated foamed nickel as a working electrode, placing the working electrode in an electro-deposition solution for cyclic voltammetry electro-deposition, and sequentially washing and drying after the reaction is completed to obtain a nickel-cobalt sulfide compound material; wherein the surfactant is prepared from any one or more of lauryl sodium sulfate, polyvinylpyrrolidone and cetyltrimethylamine bromide. The nickel-cobalt sulfide compound material is prepared by adopting a method of combining the surfactant and cyclic voltammetry electrodeposition, the method is short in preparation time and low in energy consumption, and the prepared nickel-cobalt sulfide compoun
