Highly selective CO2 capture on N-doped carbon produced by chemical activation of polypyrrole functionalized graphene sheets

Abstract

N-doped porous carbon produced via chemical activation of polypyrrole functionalized graphene sheets shows selective adsorption of CO2 (4.3 mmol g(-1)) over N-2 (0.27 mmol g(-1)) at 298 K. The potential for large scale production and facile regeneration makes this material useful for industrial applications.
