The electrooxidation of chemisorbed co on polycrystalline platinum: A mechanistic interpretation of the anodic current peak multiplicity

The electrooxidation of CO on polycrystalline Pt in 1 <i>M</i> HClO<sub>4</sub> at 23°C under potentiodynamic conditions exhibits a double current peak. Whether a single or a double current peak is formed depends to a great extent on the amount of CO surface coverage. The pre...

Sumario:The electrooxidation of CO on polycrystalline Pt in 1 <i>M</i> HClO<sub>4</sub> at 23°C under potentiodynamic conditions exhibits a double current peak. Whether a single or a double current peak is formed depends to a great extent on the amount of CO surface coverage. The present report attempts to explain the behaviour of the electrochemical reaction in terms of a single model involving the participation of two CO adsorbed states on polycrystalline Pt.
