掺氮石墨烯的制备及其ORR催化性能的研究

SYNTHESIS OF NITROGEN-DOPED GRAPHENE FOR OXYGEN REDUCTION REACTION

  • 摘要: 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。

     

    Abstract: 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 techniques, such as Raman, TEM are introduced. Electrical measurements demonstrate that products have higher catalytic performance for Oxygen Reduction Reaction in an alkaline solution.
