%X This work describes a facile approach to modify metal¨Corganic frameworks (MOFs) with ionic liquids (ILs), rendering them as useful heterogeneous catalysts for CO2 chemical fixation. An amino-functionalized imidazolium-based ionic liquid is firmly grafted into the porous MOF, MIL-101¨CSO3H by the acid¨Cbase attraction between positively charged ammonium groups on the IL and negatively charged sulfonate groups from the MOF. Analyses by Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, 1H NMR, and N2 sorption experiments reveal the MOF-supported ionic liquid (denoted as [email protected]) material remains intact while functioning as a recyclable heterogeneous catalyst that can efficiently convert CO2 and epichlorohydrin into chloropropene carbonate without the addition of a cocatalyst
