Carbon dioxide (CO2) capture and storage (CCS), and conversion is the key route to reduce the atmospheric CO2 level and utilization of carbon sources to obtain value-added products or fuels. The transformation of CO2 into the cyclic carbonates by the fixation of CO2 via cycloaddition with epoxides is important in aspects of global carbon management and resource utilization. It is highly desirable to develop an efficient catalyst with high catalytic activity and reusability for epoxide/CO2.Herein, various amino acid functional groups immobilized Mn(III)-porphyrin metal-organic frameworks, PCN-222(Mn)-NH2-OH, were synthesized and utilized as an effective catalyst for the CO2 cycloaddition into epoxides. The developed catalyst possesses acid-base dual functionality as active sites, which activate both epoxides as well as CO2 simultaneously to carry out the cycloaddition reaction. The catalyst showed a maximum yield up to 99 % with >99% of selectivity. |
