Fund Project: The authors are grateful for the financial supports of 973 Program, National Science and Technology Commission, China (G2000026408), the National Natural Science Foundation of China (20003005), Natural Science Foundation Jilin Province, (20000510) and Natural Science Foundation Jiangsu Province, (BQ2000009).

The promoter effects of rare earth ions on the electrocatalytic oxidation of methanol at the Pt electrode were studied using the cyclic voltammetry and stable polarization techniques. It was found for the first time that Eu Ho Dy ions could accelerate the electrocatalytic oxidation of methanol at the Pt electrode, while Lu Pr Yb Sm ions showed inhibitor effects.
