Construction and Adsorption Properties of an Amide-based Cu-MOF
【摘要】 利用无机铜盐与5-(异烟酰胺基)间苯二甲酸,通过溶剂热合成法制备了一种新的金属有机骨架材料[Cu(C14H7N2O5)]·5H2O·DMF;通过单晶X射线衍射(SCXRD)、热重分析(TG)、傅里叶变换红外光谱(FTIR)及气体吸附测试表征了该化合物的微观结构和基本物理化学性质.SCXRD分析结果表明,该化合物具有由Kagome层状结构组成的三维结构;N2等温吸附-脱附测试结果表明,该化合物具有889.21 m2/g的BET比表面积和永久孔隙;理想吸附溶液理论(IAST)计算结果表明,该化合物对等摩尔CO2/CH4混合气体的分离比为5.52,说明该化合物能够有效分离CO2/CH4混合气体.
【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.
