A Calcium Coordination Framework Having Permanent Porosity and High CO2/N2 Selectivity
Journal Article

· Crystal Growth and Design
A thermally stable, microporous calcium coordination network shows a reversible 5.75 wt % CO{sub 2} uptake at 273 K and 1 atm pressure, with an enthalpy of interaction of {approx}31 kJ/mol and a CO{sub 2}/N{sub 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.
