NOVELTY - The preparation method of graphene involves adding quartz boat and other quartz boat to a graphite oxide vessel, uniformly mixing, placing the mixture in a tubular furnace and then heating under a heating rate of 10 degrees C/minute in the presence of argon gas as protective gas, increasing the temperature at 200-1000 degrees C for 1 hour, and naturally cooling to room temperature. USE - The method is useful for preparation of graphene (claimed). ADVANTAGE - The method enables preparation of graphene with high specific surface area and excellent heat stability and adsorption performance.
