▎ 摘  要

NOVELTY - Nitrogen-doped graphene material preparation involves adding micro-molecule fatty amine aqueous solution in the ultrasonic dispersion of aqueous graphite oxide solution for performing hydro-thermal reaction for 36-72 hours. The concentration of the graphene oxide in aqueous graphite oxide solution is 5 g/L. The concentration of micro-molecule fatty amine in micro-molecule fatty amine aqueous solution is 1-3 mol/L. The product is precipitated, washed and dried to obtain the nitrogen-doped graphite material. USE - Method for preparing nitrogen-doped graphene material (claimed) used for separation and purification of product. ADVANTAGE - The method enables preparing nitrogen-doped graphene material with good catalytic activity.
