NOVELTY - Method for preparing nitrogen-doped graphene material based on 3,5-diamino-1 H-1,2,4-triazole, involves dispersing graphene in deionized water, adding an aqueous solution of 3,5-diamino-1 H-1,2,4-triazole, heating at 50-100 degrees C for 30-60 minutes, cooling to 0-4 degrees C to obtain graphene-coated 3,5-diamino-1 H-1,2,4-triazole eutectic, grinding into powder, and heating tubular furnace at 500-800 degrees C for 3-5 hours to obtain a nitrogen-doped graphene material, where the mass ratio of the graphene to 3,5-diamino-1 H-1,2,4-triazole in the aqueous solution of 3,5-diamino-1 H-1,2,4-triazole is 1:(1-10). USE - Method for preparing nitrogen-doped graphene material based on 3,5-diamino-1 H-1,2,4-triazole. ADVANTAGE - The method obtains graphene material with high nitrogen doping content, eliminates the need of adhesives and other additives, and completely maintains the surface properties of 3,5-diamino-1 H-1,2,4-triazole crystals.
