Synthesis and Research of Metal-organic Frameworks Materials Based on 4-(Tetrazol-5-yl)Benzoic Acid and 3, 5-Dimethyl-1,2,4-triazole

采用4-(四氮唑-5-次甲基)苯甲酸和3,5-二甲基-1,2,4-三氮唑混配体和Zn2+构筑的车辅式双核结构单元,分别进行了红外光谱(IR)分析,X-射线粉末衍射(PXRD)测试,吸附测试(ASAP-2020),热重测试(TGA),荧光测试,溶剂稳定性测试,该材料对N2和CO2吸附较高,是一种非常具有前景的储存气体材料。

Metal-organic framework material with paddle-wheel binuclear structure was synthesized by using 4-（tetrazol-5-yl） benzoic acid and 3, 5-dimethyl-1, 2, 4-triazole（Hdmtrz） as mixed ligand and metal Zn2＋ under solvothermal conditions. Then it was characterized by infrared spectra（IR）, X-ray powder diffraction（PXRD） test, absorption test（ASAP- 2020）, thermogravimetric（TGA） test, fluorescence, solvent stability test. The results show that the material has high adsorption capacity for N2 and CO2, and is a kind of promising gas storage material.
