Fabrication of graphene–fullerene porous carbons

Abstract

A novel porous carbon was fabricated by intercalating fullerene between graphene sheets. The fullerene/graphene porous composites were prepared by the lamination of graphene and fullerene, and their adsorption of water vapor was evaluated. Those with less than 10 graphene layers were hydrophobic, but the amount of water adsorbed then increased with the number of stacked layers. The simulated adsorption of water by these materials using grand canonical Monte Carlo simulations indicated that the slightly stronger interaction potentials of the composites facilitated water adsorption.
