Porous carbons with large pore volumesand surface areas providehigh performance in gas separation, water purification, and storage.Carbon composites comprising nanocarbons can offer uniform pore structureswith unique adsorption properties. In this work, we prepared fullerene-pillaredporous graphene by bottom-up processing and demonstrated its watervapor adsorption properties both experimentally and through the grandcanonical Monte Carlo simulations. Fullerene-pillared porous graphenewith 4% fullerene slightly adsorbed water vapor, and the adsorptionamount decreased on highly laminated fullerene-pillared porous graphenewith 5% fullerene owing to nanopore collapse. Fullerene-pillared porousgraphene with 25 & PLUSMN; 8% fullerene had the largest water vapor adsorptioncapacity at 40% relative humidity. On the contrary, fullerene-pillaredporous graphene with 50% fullerene showed reduced water vapor adsorption,consistent with the simulation results showing that inadequate nanospacesprevented water cluster formation because of excess fullerene molecules.Therefore, the best candidate with high adsorption capacity and uniformnanopores was found to be the fullerene-pillared porous graphene witha 25 & PLUSMN; 8% fullerene filling ratio.
