NOVELTY - Preparation of metal-structured tungsten-selenide-redox graphene composite structure comprises preparing precursor aqueous solution of tungsten diselenide film, adding single-layer graphene oxide aqueous solution and citric acid to precursor aqueous solution of tungsten diselenide film, performing hydro-thermal treatment on tungsten diselenide-reduced graphene oxide precursor aqueous solution at 165-180 degrees c, inserting polyethylene naphthol substrate to tungsten diselenide-reduced graphene oxide precursor aqueous solution to obtain thin-film-shaped metal-structured tungsten-selenide-redox graphene composite structure, filtering, washing precipitate in residual solution after hydrothermal treatment and drying. The mass ratio of single-layer graphene oxide to tungsten diselenide is 0.025-0.05. USE - The method is for preparation of metal-structured tungsten-selenide-redox graphene composite structure. ADVANTAGE - The method has simple process, low cost of raw materials and equipment, low energy consumption and high efficiency.
