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

► {[Cu3(BTB)2(H2O)3]⋅(DMF)9(H2O)2} MOF with very good structural properties obtained. ► Gas sorption of CO2, CH4, and N2 as a single-gas on the MOF-14 material was studied. ► Adsorption of CO2/CH4 and CO2/N2 gas mixtures on obtained copper MOF was presented. ► We report a water-exposure influence on a copper carboxylate framework MOF-14.
