The invention discloses a method for preparing a nitrogen-doped graphene material with a hydrothermal process, relating to a method for preparing the nitrogen-doped graphene material. The technical problems of lower nitrogen content, difficulty in control of nitrogen content, high production cost, complex structure of equipment required by reaction, rigorous reaction conditions, low yield, difficulty in industrialized production and the like in the traditional method for preparing the nitrogen-doped graphene material are solved in the invention. The method comprises the steps of: 1, dissolving graphite oxide in a solvent, adding a surfactant and uniformly mixing; 2, adding a nitrogen-containing compound, and uniformly mixing; and 3, after a hydro-thermal reaction, washing and drying to obtain the nitrogen-doped graphene material. The nitrogen-doped graphene material prepared in the invention has the advantages of higher nitrogen content, controllable nitrogen content, low production cost, simple structure of required equipment, high yield and easiness in realizing industrialized production.
