Abstract
The effects of underpotentially deposited Pb on the oxidation of sodiu m lactate at a Pt electrode was studied by recording cyclic voltammogr ams. The activity of the modified electrode towards the electro-oxidat ion of sodium lactate in alkaline solution was found to be higher than that of bulk platinum. A deactivation of the electrocatalyst was obse rved when the pyruvate concentration was high, suggesting its preferen tial adsorption on the catalyst.
