Much of the efficient efforts have been largely devoted to enhancing the CO₂ binding affinity in MOFs. In this paper, three isoreticular triazolate frameworks with the formula LIFM-1(TAZ).solvents, LIFM-1(MTAZ).solvents and LIFM-1(AmTAZ).solvents (TAZ = 1,2,4-triazole; MTAZ = 3-methyl-1H-1,2,4-triazole; AmTAZ = 3-amino-1H-1,2,4-triazole) have been prepared by using divalent zinc ions with the ligands of TAZ and its amino and methyl substituted derivatives for comparison of their sorption properties. High thermal stability and phase purity of the three MOFs were verified by thermogravimetric analysis and powder X-ray diffraction, respectively. Single component adsorption isotherms of N₂, CO₂ and H₂ were also measured experimentally. Virial method shows that the porous frameworks of LIFM-1(AmTAZ) display high selectivity of CO₂ over N₂.

许多有效的努力主要致力于提高MOF中的CO ₂结合亲和力。本文研究了三种等网状三唑骨架，其分子式为LIFM-1（TAZ）。溶剂，LIFM-1（MTAZ）。溶剂和LIFM-1（AmTAZ）。溶剂（TAZ = 1,2,4-三唑; MTAZ = 3-甲基-1H-1,2,4-三唑; AmTAZ = 3-氨基-1H-1,2,4-三唑）是通过使用具有TAZ及其氨基和甲基取代衍生物的配体的二价锌离子制备的比较它们的吸附性能。分别通过热重分析和粉末X射线衍射验证了三种MOF的高热稳定性和相纯度。N ₂，CO ₂和H _2的单组分吸附等温线还通过实验进行了测量。病毒方法表明，LIFM-1（AmTAZ）的多孔骨架对N ₂表现出较高的CO ₂选择性。
