Chemical functionalization strategies for carbon dioxide capture in microporous organic polymers

Abstract

Abstract We review the design and use of microporous polymers for pre‐ and post‐combustion capture of CO 2 . Microporous organic polymers are promising candidates for CO 2 capture materials. They have good physicochemical stabilities and high surface areas. Ultrahigh‐surface‐area microporous organic polymers could find use in pre‐combustion capture, while networks with lower surface areas but higher heats of sorption for CO 2 might be more relevant for lower pressure, post‐combustion capture. We discuss strategies for enhancing CO 2 uptakes including increasing surface area, chemical functionalization to provide high‐enthalpy binding sites and the potential for pore size tuning. © 2013 Society of Chemical Industry
