ABSTRACT:
In this paper two types of electrode materials, graphite and expanded graphite as support material have been used. The graphite plate electrode was expanded by doping with potassium (K)-vapour using vapour incorporation technique. After that the expanded graphite and normal graphite electrodes were platinised by simple galvanostatic electro-deposition technique. In this article catalytic activities of the electrodes towards ethanol have been measured using cyclicvoltammetry technique at different scan rates and amperometry technique. It is observed that anodic peak potentials as well as the corresponding peak currents changed with scan rate. It is also found that oxidation current of the alcohol using the expanded graphite as the support material are higher. Amperometry studies shows that expanded support electrocatalyst is more durable than unexpanded support electrocatalyst. So Pt deposited on potassium expanded graphite acts as a better electrocatalyst.
