NOVELTY - Preparing graphene, comprises reacting graphite oxide solution with metal liquid ammonia, purifying, and separating to obtain the product. USE - The method is used in the field of electrochemistry. ADVANTAGE - The method reduces the formation of graphite oxide completely; easily separates the product; has simple purifying process; does not utilize any stabilizing and dispersing agents; utilizes less impurity elements, reducing agents, and simple equipment; has controllable conditions, where it can control low temperature reduction conditions for preventing agglomeration; and has short reaction period, and normal pressure conditions.
