Herein, an aminoethylimidazole IL-modified MOF catalyst with multiple catalytic active sites (denoted as MIL-101-NHIM-NH₂) was synthesized through an aldimine condensation post-synthesis method. Through thorough characterizations, such as FT-IR, XRD, SEM-EDS mappings, N₂ adsorption and desorption, XPS, elemental anal. and TG measurement, the results showed that the surface of MIL-101-NHIM-NH₂ was successfully grafted with the ionic liquid Owing to the synergistic effects of multiple active sites containing Cr, -NH₂ and Br- in the MIL-101-NHIM-NH₂ catalyst, MIL-101-NHIM-NH₂ could efficiently catalyze the cycloaddition reaction of CO₂ and epoxide without addnl. solvent and cocatalyst; 93.5% of propylene carbonate was obtained at 120°C, 2 MPa and 4 h.
