Adsorption study of CO2, CH4, N2, and H2O on an interwoven copper carboxylate metal-organic framework (MOF-14).

Metal-organic frameworks (MOFs) are attractive microporous materials for adsorption separations due to their extraordinary structures and impressive high surface areas. Catenation, or framework interpenetration, can significantly impact the crystal stability and improve the adsorption interactions. This interesting approach was used to obtain {[Cu(3)(BTB)(2)(H(2)O)(3)]·(DMF)(9)(H(2)O)(2)} (MOF-14) as a microporous material with a high surface area and large pore volume, which are desirable parameters for adsorption applications.
