由于掺氮石墨烯具有优异的电化学性能，受到研究者的关注，然而在石墨烯掺氮的方法中大部分（热解法、烧结法）需要过高的温度（500~900℃）和较长的反应时间（2~3 h）[1-3]。采用微波等离子体对氧化石墨进行还原改性制备掺氮石墨烯，在低功率条件下反应时间只需20 min就得到了催化活性良好的掺氮石墨烯。掺氮石墨烯的表征技术主要包括Raman和TEM，并使用电化学工作站对掺氮石墨烯进行ORR催化性能评估。

Some outstanding properties of nitrogen-doped graphene has attracted much attention.The most synthesis methods of nitrogen-doped graphene need high temperature and long time which wiil destroy the structure of graphene and weaken the performance. In this article,we propose nitrogen plasma discharge method for synthesis of N-doped graphene sheets by simultaneous N-doping and reduction of graphene oxide(GO)sheets. Meantime,various characterization tech-niques,such as Raman,TEM are introduced. Electrical measurements demonstrate that products have higher catalytic per-formance for Oxygen Reduction Reaction in an alkaline solution.
