Thermally activated construction of open metal sites on a Zn-organic framework: An effective strategy to enhance Lewis acid properties and catalytic performance for CO2 cycloaddition reactions

For the synthesis of cyclic carbonates from CO2 and epoxides, coordinatively unsaturated metal sites of metal–organic frameworks (MOFs) could play a vital role as active Lewis acid centers for facilitating the ring-opening of epoxides. Hence, constructing open metal sites (OMSs) on MOFs will be an effective strategy to improve their catalytic activity for the CO2 cycloaddition reaction. Herein, a simple thermal treatment method is performed on...
