▎ 摘  要

NOVELTY - Preparation of nitrogen-doped graphene comprises adding graphite oxide to deionized water at mass volume ratio of 0.5-1 mg: 1 ml, ultrasonically processing for 1 hour, adding pyrrole, mixing, adding ammonium sulfate, stirring for 10-20 hours, filtering, cleaning and drying to obtain oxidized graphene-pyrrole mixture, heating mixture to 70 degrees C under oxygen free atmosphere, incubating at 50 degrees C for 0.5-2 hours, and cooling. The mass ratio of pyrrole and graphite oxide is 0.2:1 to 1:1. The mass ratio of ammonium sulfate and pyrrole is 0.01:1 to 0.05:0.2. USE - Method for preparing nitrogen-doped graphene. ADVANTAGE - The prepared graphene has high nitrogen content.
