NOVELTY - Preparation of nitrogen-doped graphene comprises mixing porogen and graphite oxide at mass ratio of 0.01-0.5:1, and dissolving in water to obtain 0.1-10 g/L mixed solution; filtering, collecting filtrate, and drying to obtain powder; and subjecting to reduction treatment at 500-580 degrees C for 1-30 minutes under inert gas protective atmosphere, and cooling to room temperature while stopping inert gas. USE - Method for preparation of nitrogen-doped graphene (claimed). ADVANTAGE - The method is easy to operate, and has wide source of raw materials, low cost, and no special requirements for equipment.
