Metal beta-diketonate complexes as highly efficient catalysts for chemical fixation of CO2 into cyclic carbonates under mild conditions

摘要

The potential of metal beta-diketonate complexes for the catalysis of the chemical fixation of CO2 into cyclic carbonates at 1 atm CO2 and near room temperature was demonstrated. Their potential for the capture and simultaneous conversion of CO2 in a dilute CO2 stream was also determined. The catalysts were easily synthesized and commercially available. Therefore, this CO2 transformation was less energy- and material-consuming, which made this reaction closer to true "green" chemistry.
