dc.description.abstract |
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. |
