Abstract:

A novel metal-organic framework, [Cu(C14H7N2O5)]·5H2O·DMF, was synthesized by solvothermal method with inorganic copper salt and 5-(isonicotinamide) mbenzoic acid as starting materials. The microstructure and basic physical and chemical properties of the compound were characterized by means of single crystal X-ray diffraction(SCXRD), thermogravimetric analysis(TG), Fourier transform infrared spectroscopy(FTIR), as well as gas adsorption and separation. Single crystal diffraction analysis showed that the compound has a 3D structure consisting of Kagome layered structure. Nitrogen isothermal adsorption-desorption test showed that the compound has a high BET surface area of 889.21 m2/g and permanent porosity. The gas separation ratio of the compound is calculated to be 5.52 by the ideal adsorbed solution theory(IAST), indicating that the compound could effectively separate CO2/CH4 gas.
