▎ 摘  要

NOVELTY - Preparing nitrogen-doped graphene material involves mixing graphene oxide and nitrogen-containing compound to obtain homogeneous mixture, and adding solvent to homogeneous mixture to obtain graphene oxide/nitrogen-containing compound composite. The graphene oxide/nitrogen-containing compound composite is heated at 400-1500 degrees C with heating rate of 1-100 degrees C/minute for 5 seconds to 30 minutes. USE - Method for preparing nitrogen-doped graphene material (claimed). ADVANTAGE - The method enables to prepare nitrogen-doped graphene material with high electrochemical performance in a cost-effective manner.
