Abstract:

A Fe-MOF(metal-organic framework)(1) was synthesized using 4,4′,4″-(9H-carbazole-3,6,9-triyl)-tribenzoic acid(H3L) and [Fe3μ3-O)(CH3COO)6] cluster under solvothermal condition. The structure of the ompound 1 was characterized by X-ray crystallography. Compound 1 possessed a 3D framework with a high specific area. The IAST(Ideal Adsorbed Solution Theory) selectivity of compound 1 towards CO2/CH4 (volume ratio 0.5∶0.5) is 3.52(273 K) and 3.15(298 K), respectively. Gas sorption experiments reveal that compound 1 can serve as a candidate for CO2/CH4 separation.

Key words: Metal-organic framework(MOF), Fe-based MOFs, Carbazole, Gas sorption and separation
