NOVELTY - Preparation of porous graphene involves dissolving ammonium salt and glucose in deionized water, obtaining a mixed solution, adding 1.8-2.2 g/L graphene oxide aqueous solution, stirring, drying into paste at 30-50 degrees C, obtaining a paste mixture, placing the paste mixture in protective atmosphere, heating from room temperature to 900-1000 degrees C for 2-4 hours, and heat-preserving for 1-2 hours. The weight ratio of ammonium salt, glucose and deionized water is 0.6-1.2:0.4-0.8:5. The weight ratio of the ammonium salt and the graphene oxide aqueous solution is 10:0.6-1.2. USE - Preparation of porous graphene (claimed). ADVANTAGE - The method enables preparation of porous graphene having excellent electroconductivity. The porous graphene can be used directly, and is easy to use.
