NOVELTY - The preparation of graphene diselenide nickel composite material involves mixing reducing agent and graphene oxide solution, adding PTFE-lined stainless steel into reaction kettle, stirring to form brown solution, adding selenium comprising material containing nickel and inorganic salt into reaction kettle, reacting a closed reactor, naturally cooling after reaction, filtering reaction mixture, repeatedly washing with distilled water and ethanol, filtering, collecting product and drying after storage. USE - Preparation of graphene diselenide nickel composite material (claimed). ADVANTAGE - The method enables industrial production of economical and environmentally-friendly graphene diselenide nickel composite material at low reaction temperature. The composite material has high specific surface area.
