摘要

A double active center system,namely Salen-Cu(ll)@MIL-101(Cr),was successfully synthesized via the "ship in a bottle" approach,which acted as a bifunctional material for both capture and conversion of CO2 in a single process.For the first time,Salen-Cu(Ⅱ)@MIL-101(Cr) catalyst was developed for the synthesis of propylene carbonate from CO2 and propylene oxide under room temperature and ambient pressure with a yield of 87.8％ over 60 h.Furthermore,the reaction mechanism was also discussed.
