Abstract:

Under atmospheric pressure,nano-sized cerium dioxide (CeO2) was prepared by chemical precipitation method.Catalyzed by this nano-sized CeO2,dimethyl carbonate (DMC) was synthesized directly from carbon dioxide and methanol (CH3OH).The effects of reaction temperature,carbon dioxide pressure and the dosage of CeO2 on the yield of DMC were investigated.The results showed that the highest yield was 47.9% at 140 ℃ with carbon dioxide pressure 4.0 MPa,catalyst dosage 0.15 g,and  the amount of CH3OH 15 mL.

Key words: cerium dioxide, nano meter, catalyst, dimethyl carbonate
