NOVELTY - Method for preparing a nitrogen-cobalt co-doped graphene material based on 4-amino-1,2,4-triazol-5-one cobalt salt, involves (a) dispersing graphene in deionized water, adding an aqueous solution of 4-amino-1,2,4-triazol-5-one cobalt salt, heating at 50-100 degrees C for 30-60 minutes, and cooling to 0-4 degrees C, drying to obtain 4-amino-1,2,4-triazole-5-one cobalt salt eutectic coated with graphene, grinding into powder, and heating in a tube furnace at 500-800 degrees C for 3-5 hours to obtain graphene material co-doped with nitrogen and cobalt, where the mass ratio of 4-amino-1,2,4-triazol-5-one cobalt salt in the aqueous solution of graphene and 4-amino-1,2,4-triazol-5-one cobalt salt is 1:(1-10). USE - The method is used for preparing a nitrogen-cobalt co-doped graphene material. ADVANTAGE - The prepared graphene material is uniformly coated on the surface of the 4-amino-1,2,4-triazol5-one cobalt salt crystal, free of adhesive and maintains the surface performance of 4-amino-1,2,4-triazol-5-one cobalt salt crystal.
