SYNTHESIS OF NITROGEN-DOPED GRAPHENE FOR OXYGEN REDUCTION REACTION

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.
