摘要：

The electrocatalytic effect of some metal ad-atoms (Pb, Tl, Cd) on ethanol oxidation were investigated at a Pt electrode in alkaline medium. All three metal ad-atoms enhance the electrocatalytic activity of Pt. Pb and Tl ad-atoms increase the oxidation rate by a factor of about 15, whereas Cd ad-atoms shift the polarization curves negatively giving a factor of about 5 at lower overpotentials.
