Abstract
A method of preparing a three-dimensional graphene structure, and a graphene structure prepared by the method are provided. The method includes preparing a dispersion in which a graphite oxide is dispersed, and preparing a gel by controlling a degree of reduction of the dispersion. The method can be useful in providing a three-dimensional graphene structure having a specific surface area, a pore size or a volume per unit mass, which is suitable for the field of applications thereof.
