▎ 摘 要
NOVELTY - Method for preparing nitrogen-doped graphene using component (A) comprising organic salt compound containing a halogen anion, component (B) comprising monosaccharide compound, and component (C) comprising nitrogen-containing compound. USE - The method is useful for preparing nitrogen-doped graphene. ADVANTAGE - The method does not need to use any organic solvent. The nitrogen-doped graphene has large specific surface area, high nitrogen content and uniform structure.
