摘要：

The electrooxidation of CO adsorbate on well ordered Pt(111) surfaces is studied through a flow-cell technique. Potentiodynamic sweeps and potential steps are used to characterize the kinetic behaviour of the adsorbate. The effect of surface disturbance when the electrode is cycled into the oxide formation region is analysed. The oxidation of CO is faster in the case of disturbed surfaces. The results are interpreted in terms of a simple kinetic model.
