摘要: The present invention relates to a nitrogen-doped 3-D porous graphene assembly and a method of preparing the same. The present invention provides a method of preparing a nitrogen-doped graphene assembly, the method including the steps of mixing a graphene oxide solution with a melamine solution, freezing the mixed solution of graphene oxide and melamine, drying the frozen solution in a frozen state to prepare a graphene assembly, and heating the graphene assembly at a predetermined temperature under the argon atmosphere for a predetermined to time, in which a mass ratio of the graphene oxide and the melamine in the mixed solution is 19:1 to 4:1. According to the present invention, a uniformly nitrogen-doped 3-D porous graphene assembly may be synthesized.
