Imidazolium ionic liquids functionalized UiO-66-NH₂ MOFs were synthesized by two different approach, further applied as efficient catalysts for the catalytic conversion of CO₂ into cyclic carbonates. The functionalized UiO-66-NH₂ were investigated using various characterization technologies including XRD, NMR, FT-IR, XPS, TG-DTG, TEM, N₂-adsorption, and NH₃-TPD. The octahedron structure of UiO-66-NH₂ becomes rough after UiO-66-NH₂ interacted with 1-(4-carboxybutyl)-3-methylimidazolium bromide via amidation, while some small grains were formed around UiO-66-NH₂ species when UiO-66-NH₂ was functionalized by 1-(3-sulfopropyl)-3-methylimidazolium bromide ([SPMIM]Br) via the H₂N– and HSO₃– interaction. Moreover, when [SPMIM]Br was grafted onto the surface of UiO-66-NH₂, a higher catalytic activity was found to exhibit 98.12% conversion of epichlorohydrin (ECH) and 98.23% selectivity to chloropropene carbonate (CPC) under optimized conditions (Initial pressure 2.5 MPa, 1.2 wt% catalyst of ECH, 95 °C, reaction time 8 h). No significant deactivation of the catalyst was observed after the [SPMIM]Br functionalized UiO-66-NH₂ was reused three times. Furthermore, several additional coupling reactions were investigated with other epoxides as substrates.

通过两种不同的方法合成了咪唑鎓离子液体官能化的UiO-66-NH ₂ MOF，并进一步用作将CO ₂催化转化为环状碳酸酯的有效催化剂。使用各种表征技术，包括XRD，NMR，FT-IR，XPS，TG-DTG，TEM，N _2-吸附和NH ₃ -TPD ，对官能化的UiO-66-NH ₂进行了研究。UiO-66-NH ₂通过酰胺化作用与1-（4-羧丁基）-3-甲基咪唑鎓溴化物相互作用后，UiO-66-NH ₂的八面体结构变得粗糙，而在UiO-66-NH ₂物种周围形成了一些小晶粒当UiO-66-NH ₂通过H ₂ N–和HSO ₃ –的相互作用被1-（3-磺丙基）-3-甲基咪唑溴化物（[SPMIM] Br）官能化。此外，当[SPMIM] Br接枝到UiO-66-NH ₂的表面上时，发现在最佳条件下，较高的催化活性表现出98.12％的表氯醇（ECH）转化率和98.23％的选择性生成碳酸氯丙烯（CPC）（初始压力2.5 MPa，ECH催化剂的1.2 wt％，95°C，反应时间8 h）。[SPMIM] Br官能化的UiO-66-NH ₂重复使用3次后，未观察到催化剂的明显失活。此外，还研究了其他环氧化物作为底物的几种其他偶联反应。
