NOVELTY - Preparation of iron-cobalt bimetallic single-atom anchoring azagraphene cocatalyst involves adding graphene oxide into deionized water and ultrasonically mixing, adding mixed solution of cobalt chloride aqueous solution and ferric chloride aqueous solution and ultrasonically dispersing in the mixed solution to obtain first solution, putting first solution into liquid nitrogen for quick freezing and freeze-drying for 48 hours, calcining at high temperature for 1 hour in an atmosphere of argon and ammonia to obtain aza-graphene anchored with iron-cobalt bimetallic single atoms, as a co-catalyst, performing dipping method, adding load material into anhydrous ethanol solution, ultrasonically dispersing and combining with aza-graphene anchored with iron-cobalt bimetallic single atoms, mechanically stirring at room temperature for 6-8 hours, centrifuging and washing and vacuum-drying at 60degrees Celsius for 6-8 hours, and grinding dried product and annealing. USE - Preparation of iron-cobalt bimetallic single-atom anchoring azagraphene cocatalyst e.g. mesoporous graphitic carbon nitride nanomaterials of iron-cobalt bimetallic single-atom-anchored azagraphene used in photocatalytic hydrogen production (claimed). ADVANTAGE - The method provides the mesoporous graphitic carbon nitride nanomaterials of iron-cobalt bimetallic single-atom-anchored azagraphene cocatalyst having excellent photo-catalytic hydrogen production performance.
