摘要：

The adsorption of carbon oxides from sulfuric acid solution on a palladium electrode was investigated with electrochemical and radiometric methods. It was found that adsorption of CO takes place in the 0.0-0.8 V range. During the CO adsorption the anodic (below 0.15 V vs. SHE) and cathodic (above 0.15 V vs. SHE) currents are passing through the solution \ electrode interface. Mechanisms for the CO adsorption and the final product structure have been proposed. A small amount of adsorbed CO2 on the surface of the palladium electrode has been observed. A strong correlation between the decrease in the real surface of the palladium electrode and the currents of sorbed hydrogen during its oxidation has been found.
