Cyclic voltammetry study of isopropanol elctro oxidations onto PtNi electrode

AbhikChatterjee

This article presents the electrooxidation of isopropanol on to Pt and Pt- Ni electrodes applying cyclicvoltammetry technique at different scan rates. The effect of scan rate on the electrooxidations was studied using a three electrode cell. Anodic peak potentials as well as the corresponding peak currents changed with scan rate. In cyclicvoltammetric experiments a gradual increase of the oxidation peaks with the increasing scan rate has been observed and shifts the peak potential in the positive direction. It is also seen that the isopropanol (2-PrOH) electrooxidation onto Pt and PtNi electrode is irreversible in nature.
