NOVELTY - Method for synthesizing nitrogen-doped graphene from solid organic acid, involves (a) mixing solid organic acid and catalyst with a nitrogen-containing small molecule, (b) placing the mixture in a reactor protected with an inert or reducing gas, reacting, and cooling to room temperature under the same atmosphere to obtain a solid product, and (c) washing the solid product, filtering, and drying to obtain the graphene. USE - The method is useful for synthesizing nitrogen-doped graphene from solid organic acid. ADVANTAGE - The method adopts simple and economical process, and has no pollution, and is suitable for large-scale preparation.
