NOVELTY - Preparing disulfide/nitrogen-doped graphene nanocomposite material involves mixing iron disulfide precursor solution and graphene oxide. The obtained mixture is carried out with hydro-thermal reaction to form disulfide/nitrogen-doped graphene nanocomposite material. USE - Method for preparing disulfide/nitrogen-doped graphene nanocomposite material used for preparing hydrogen evolution electro-catalysis and electrode material (claimed). ADVANTAGE - The method enables to prepare disulfide/nitrogen-doped graphene nanocomposite material with high conductivity.
