基于4-（四氮唑-5-次甲基）苯甲酸和3,5-二甲基-1,2,4-三氮唑构筑的金属-有机骨架合成与研究

摘要

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.
