Abstract
A facile mechanochemical intercalation approach was adopted to immobilize ionic liquids into layered materials. The immobilized ionic liquids were found to be useful as catalysts for the coupling reaction of CO2 and propylene oxide to synthesize propylene carbonate. The immobilized ionic liquid exhibited similar reactivity as the free ionic liquid. Overall, the 10 mechanochemical approach proves to be effective in immobilizing ionic liquids in layered compounds and thus may expand the applications of ionic liquids and, meanwhile, improve catalyst separation and recycling.
