NOVELTY - Preparing 5,5'-diamino-3,3'-bis-1,2,4-triazole based nitrogen-doped graphene material comprises dispersing graphene in N,N'-dimethylformamide, adding N,N'-dimethylformamide solution of 5,5'-diamino-3,3'-bis-1,2,4-triazole, heating at 50-100 degrees C for 30-60 minutes, cooling to 0-4 degrees C, drying to obtain graphene-coated 5,5'-diamino-3,3'-bis-1,2,4-triazole crystal; grinding it into powder, placing it in tubular furnace heated at 500-800?poC for 3-5 hours to obtain nitrogen-doped graphene material; where the mass ratio of graphene to 5,5'-diamino-3,3'-bis-1,2,4-triazole is 1:1-10. USE - The method is useful for preparing 5,5'-diamino-3,3'-bis-1,2,4-triazole based nitrogen-doped graphene material. ADVANTAGE - The method: can evenly coats graphene on surface of 5,5'-diamino-3,3'-bis-1,2,4-triazole crystals, does not uses additives e.g. adhesive; and completely maintains 5,5'-diamino-3,3'-bis-1,2,4-triazole crystal surface properties.
