Abstract

Herein, we developed a tri-functional MOF heterogeneous catalyst, MIL-IMAc-Br-, by a post-synthesis modification method for the first time. Due to the synergistic role of three functional sites, including Lewis acid sites, Brønsted acid sites and Br- anion sites, MIL-IMAc-Br- displayed an efficient catalytic performance for the cycloaddition reaction of CO2 and epoxides to form cyclic carbonates under mild and co-catalyst free conditions.
