Chemical conversion of CO2 into cyclic carbonates using a versatile and efficient all-in-one catalyst integrated with DABCO ionic liquid and MIL-101(Cr)

A novel heterogeneous catalyst, MIL-101(Cr)-DABCO IL, with DABCO serving as bridge agent to merge the advantages of ionic liquids (IL) and metal-organic framework (MOF) was prepared and evaluated as catalyst for the synthesis of cyclic carbonates from CO2 and epoxides. The coordinatively unsaturated Cr(III) nodes in MOF framework function as specific centers to chelate tertiary N atom in DABCO, which offers a bridge that has strong affinity to...
