| description | A modification of platinum-polyvinyl chloride (Pt-PVC) electrode for the electrooxidation of ethanol in alkaline solution
has been investigated. Pt-PVC electrode was prepared by mixed together platinum metal powder with PVC (95:5 w/w),
homogenized, added with tetrahydrofuran to dissolved the dried, put into 1 cm diameter mould and press at 10 ton/cm2.
Studies on electrochemicals behavior for Pt-PVC electrode were carried out using cyclic voltammetry and chronocoulometry
modes. The higher current density for hydroxide adsorption peak were recorded, 0.25 mA/cm2 and 85 mA/cm2 respectively
when Pt-PVC electrode was used compared to Pt electrode. This indicates that Pt-PVC electrode gives better conductivity
and electrochemical behavior to electrooxidation of ethanol in KOH compared to Pt electrode. Result obtained shows the
used of Pt-PVC electrode for electrooxidation of 0.25 M ethanol in 1.0 M KOH supporting electrolyte increased the
percentage of acetic acid produced compared to Pt electrode. |
