Abstract
A method for making graphene-based highly dense but porous carbon material with a high degree of hardness includes forming a sol by dispersing a graphene-based component in a solvent; preparing a graphene-based gel by reacting the sol in a reacting container at a temperature of about 20° C. to about 500° C. for about 0.1 hours to about 100 hours; and drying the gel at a temperature of about 0° C. to about 200° C. to obtain a material. A graphene-based porous carbon material and applications thereof are also disclosed.
