Carbon dioxide(CO_2) , as the major greenhouse gas,had shown its powerful impact on global warming and a series of environmental issues.To eliminate the CO_2 emission and retain the balance of carbon cycle, the conversion of CO_2 into value added products via chemical fixation methods had attracted booming interests.The emerging metal-organic frameworks(MOFs) possessing high surface area and uniform dispersed catalytic sites had been considered the powerful heterogeneous catalysts for CO_2 capture and sequential fixation.In this work, the catalytic properties of the metal-organic framework HKUST-1 in cycloaddition of CO_2 to epoxides to produce cyclic carbonates with tetrabutylammonium bromide as co-catalyst at ambient reaction condition(1 atm CO_2 and 35 ℃) were investigated. After reaction for 48 hours,HKUST-1 demonstrated efficient catalytic activity for cycloaddtion of styrene oxide with a yield of 88%over 48 hours.
