▎ 摘　　要

NOVELTY - Electrochemically preparing nitrogen-doped graphene material comprises taking alkaline solution containing ammonium salt and/or aqueous ammonia as an electrolyte solution, and graphite material as electrode, applying the alternating current between the two graphite material electrodes for electrochemical reaction to obtain nitrogen-doped graphene material from the electrolyte. USE - The method is useful for electrochemically preparing nitrogen-doped graphene material. ADVANTAGE - The method: has low cost and low requirements on equipment; and is favorable for industrial production.
