The present invention provides a method of preparing a graphene-wrapped cobalt Prussian blue nano-crystalline composite material, and a method of preparing a working electrode using the same and an application thereof. The preparation method of the composite material includes: dispersing a ligand solution containing cobalt and a graphene oxide solution in an aqueous solution fully by stirring and ultrasonication, next, adding a cobalt metal salt solution and fully stirring, and then calcining the mixture in an inert atmosphere after centrifugation and lyophilization to obtain the above composite material. The preparation method of the present invention is simple in operation, low in energy consumption and low in material costs and the like. The composite material is obtained by uniformly and closely wrapping cobalt Prussian blue nano-crystals in graphene with excellent conductivity, thereby significantly improving electron transfer efficiency and active site utilization rate of the composite material.
