Tin(IV) Sulfide Greatly Improves the Catalytic Performance of UiO‐66 for Carbon Dioxide Cycloaddition

Abstract To overcome the limitations of metal–organic frameworks (MOFs) for catalysis (e.g., low catalytic activities resulting from blockage of the active metal centers by organic linkers) is of great importance. Herein, we demonstrate the formation of UiO‐66 nanoparticles with ultrasmall size and linker defects with the aid of SnS 2 nanosheets. The UiO‐66 nanoparticles supported by SnS 2 nanosheets were found to exhibit excellent catalytic activity for the cycloaddition reaction of CO 2 with propylene oxide under solvent‐free and co‐catalyst‐free conditions. Outstandingly, the catalytic activity was 11 times higher than that of the pure UiO‐66 catalyst under optimum conditions. We thus provide a promising route to modify MOF particles thus to promote their catalytic performance.
