Abstract

A thermally stable, microporous calcium coordination network shows a reversible 5.75 wt % CO ₂ uptake at 273 K and 1 atm pressure, with an enthalpy of interaction of ∼31 kJ/mol and a CO ₂/N ₂ selectivity over 45 under ideal flue gas conditions. The absence of open metal sites in the activated material suggests a different mechanism for selectivity and high interaction energy compared to those for frameworks with open metal sites.
