    • The present invention relates to a method of preparing a nitrogen-doped graphene comprising preparing a Edge-Functionalized Graphene by binding a graphite with a organic material having amino groups and functional groups such as carboxy acid group through an electrophilic substitution reaction, and heat treating the resultant Edge-Functionalized Graphene, and a nitrogen-doped graphene prepared thereby. According to the present invention, by a more inexpensive and simpler method, a nitrogen-doped graphene can be prepared at higher purity and higher yield. The nitrogen-doped graphene obtained by the present invention has very excellent physical and electric properties, and particularly has a superior oxygen reduction capability, compared with the platinum catalyst used at cathode of a H2/O2 fuel cell so that it will replace the platinum to lower more the cost of a H2/O2 fuel cell or to increase its life and further to provide a new turning point for the commercialization of a H2/O2 fuel cell.
    • 本发明涉及一种制备氮掺杂石墨烯的方法,包括通过亲电取代反应将石墨与具有氨基和官能团如羧酸基团的有机材料结合而制备边缘官能化石墨烯,并将 由此制得的边缘官能化石墨烯和由此制备的掺氮石墨烯。 根据本发明,通过更便宜和更简单的方法,可以以更高的纯度和更高的产率制备掺杂氮的石墨烯。 本发明获得的掺杂氮的石墨烯与H2 / O2燃料电池阴极所用的铂催化剂相比,具有非常优异的物理和电学性质,特别是具有优异的氧还原能力,因此将其替代铂 降低H2 / O2燃料电池的成本或延长其使用寿命,进一步为H2 / O2燃料电池的商业化提供新的转折点。
