BACKGROUND The use of CO2 as a raw material to synthesize cyclic carbonates has attracted much attention in recent years. Ionic liquids (ILs) due to their unique properties are often used as effective catalysts for the reaction between CO2 and epoxid

A catalyst system for the efficient two-step coupling of CO2 and styrene to styrene carbonate was developed. Gold nanoparticles immobilized on multi-walled carbon nanotubes (Au/CNT) of 6 nm in diameter were used as a catalyst for the epoxidation step
