Equilibrium

CeO2 shows unique catalytic properties by an acid–base bifunctionality as well as redox properties. The acid–base bifunctional properties of CeO2 have been applied to the non-reductive CO2 conversion with alcohols such as dimethyl carbonate (DMC) synthesis from CO2 and methanol. CeO2 shows very high selectivity to DMC; however, the yield of DMC is strongly limited by the equilibrium. The combination of the synthesis of organic carbonates from CO2 and corresponding alcohols with suitable H2O removal methods can enhance the yield of the organic carbonates beyond the equilibrium limitation.
