Abstract

Efficient CO 2 scrubbing without a significant energy penalty remains an outstanding challenge for the fossil fuel-burning industry where aqueous amine solutions are still widely used. Porous materials have long been evaluated for next generation CO 2 adsorbents. Porous polymers, robust and inexpensive, show promise as feasible materials for the capture of CO 2 from warm exhaust fumes. We report the syntheses of porous covalent organic polymers (COPs) with CO 2 adsorption capacities of up to 5616 mg g -1 (measured at high pressures, i.e. 200 bar) and industrially relevant temperatures (as warm as 65 °C). COPs are stable in boiling water for at least one week and near infinite CO 2/H 2 selectivity is observed. © The Royal Society of Chemistry 2012.
