Nitrogen-Doped Graphene Oxide and Application as Electrocatalyst for PEMFC

A low time consuming and green chemistry synthesis method for preparation of nitrogen-doped graphene oxide (N/rGO) is presented. Through this paper, N/rGO was synthesized by using graphene oxide as carbon source, urea as nitrogen source and ethylene glycol as reduction agent. The effect of the reaction time on the nitrogen content of the doped materials was investigated by specific physical and chemical methods. Based on chemical properties of the prepared materials, it was found that the highest nitrogen concentration (5.86 wt.%) was obtained in mild reaction conditions (60 ° C, 30 min.).
