Design and Synthesis of ZIF‐67@DIMIL as Catalyst for CO ₂ Fixation Reaction

Abstract Conversion of CO 2 into high‐value‐added industrial raw materials, chemicals, or fuels has been considered as a way to reducing the global warming. For this purpose, imidazolium ionic liquids functionalized ZIF‐67 was designed and synthesized. The structure of functionalized ZIF‐67 was investigated using various characterization techniques including FT‐IR, FESEM, XRD, TGA, BET, and zeta potential. The exquisite combination of imidazolium ionic liquid and ZIF‐67 generated the highly robust catalyst, which was applied as efficient catalyst for the catalytic conversion of CO 2 into cyclic carbonates. Furthermore, the recyclability of catalyst was studied and the catalytic activity of ZIF‐67@DIMIL after six cycles confirmed that this catalyst can be viewed as a recyclable heterogeneous catalyst.
