CeO2–ZrO2 solid solution catalysts are very effective for the selective synthesis of propylene carbonate (PC) from propylene glycol and carbon dioxide. Dipropylene glycols and poly (PC) are expected to be formed as by-products, however, they were not detected at all in the analysis by gas chromatograph and FTIR.
CeO2–ZrO2 solid solution catalysts are very effective for the selective synthesis of dimethyl carbonate from methanol and CO2. The activity was much dependent on the calcination temperature. The higher the calcination temperature, the higher the activity of the catalyst for DMC formation, though the BET surface area is lower on the catalyst calcined at higher temperature.
