▎ 摘　　要

NOVELTY - Preparation of nitrogen-doped graphene material, involves adding graphene oxide and surfactant to distilled water, ultrasonically dispersing and mixing to obtain graphene oxide solution, adding graphene oxide solution to a nitrogen-containing compound, dissolving and stirring at room temperature to form a mixed solution, transferring into a stainless steel reactor having tetrafluoroethylene liner, then adding catalytically active metal salt, increasing the temperature, mechanically stirring, cooling, then washing repeatedly to remove ammonia and unreacted catalyst and drying. USE - Preparation of nitrogen-doped graphene material for use in catalysis, electrochemistry, energy storage and transformation applications, and electronic devices. ADVANTAGE - The preparation method is simple, and enables low cost, high yield, short period and environmentally-friendly. DETAILED DESCRIPTION - Preparation of nitrogen-doped graphene material, involves adding graphene oxide and surfactant to distilled water where the mass ratio of graphene oxide and surfactant is (1-10):1, ultrasonically dispersing and mixing to obtain graphene oxide solution having concentration of 5-30 g/L, adding the graphene oxide solution to a nitrogen-containing compound, dissolving and stirring at room temperature to form a mixed solution, transferring the obtained mixed solution into a stainless steel reactor having tetrafluoroethylene liner, then adding catalytically active metal salt, increasing the temperature to 650-1200 degrees C, mechanically stirring, cooling, then washing repeatedly to remove ammonia adsorbed on the surface of the material and to remove unreacted catalyst, and drying.
