| 摘 要： | 用循环伏安法研究了CO在Pt／C，Pt／Eu3 ／C电极上的氧化，发现吸附稀土Eu3 后。电极表面对CO的吸附明显减弱，吸附量减少．CO在电极表面的氧化过电位减小，CO的起始氧化电位负移130mV，Eu3 在电极表面的吸附对CO的氧化有电催化作用．

| Abstract: | The electrochemical behavior of CO on Pt/C and Pt/Eu3+/C electrodes in sulfuric acid solution was investigated by cyclic voltammetry. It has been found that the electrode Pt/Eu3+/C has the tendency that adsorbed CO weaker and less amount than Pt/C electrode. It also reduces the overpotential to the CO oxidation on the Pt/Eu3+/C electrode. The Pt/Eu3+/C electrode is lower onset potential about 130mV than Pt/C electrode for CO oxidation , showing that it has high electrocatalytic activity. |
