摘要
A microporous metal-organic framework (MOF), [Cd(IP)Cl](n) (1, HIP = 1H-imidazo[4,5-f][1,10]phenanthroline), with 1D square channels along the c axis was constructed through the solvothermal method. Because of the polar nitrogen atoms and the pi-electron-rich ligand, activated MOF la presents a strong interaction with CO2, showing selective capture of CO2 from a mixture of CO2/N-2. Additionally, MOF la also shows significant selective capture of CO2 from CO2/CH4 and CO2/C2H4 mixtures due to the sieving effect of the 1D channels. The column breakthrough experiment results further confirmed that microporous MOF 1a could be used as a potential porous material for selective CO2 adsorption. (C) 2018 Elsevier Ltd.
