英文摘要	The key to electrochemical conversion of carbon dioxide (CO2) into fuels lies in effient charge transfer reactions. Here, we depict from the polarzation resistance analysis that the electroreduction of CO2 to CO on manganese doped ceria (CMO) passes through two elementary charge transfer reactions. One reaction is asscociated with (CO3)(O,S)(center dot) to (CO3)(O,S)(center dot) and another associated with (CO3)(O,S)(center dot). O; S to CO. As the rate determing step, the first one has an apparenent acitvation energy of 178.7 kJ mol(-1) and a pressure dependence of (PCO2PCO0.24)-P-0.76. The second one has an apparent acitvation energy of 100.6 kJ mol(-1) and a pressure dependence of (PCO2PCO0.73)-P-0.27. Based on the experimental results, we give the kenetic expression for the CO2 electroreduction rate on CMO.
