Abstract The behaviour of acstylene black (Indian grade) as catalyst support material is reported. The acetylene black is heat treated (activated) at variour temperatures in nitrogen atmosphere. The surface area of the various heat treated samples is obtained. Platinum is deporited into the carbon bye reported technique. The of platinum agglomeration on the carbon in identified through scanning electron microscope. The above catalyst is applied to glassy carbon disc. The electrochemical surface area of the catalyst ie determined by the hydrogen absorption and oxidation in alkaline medium. Similar electrodes (disc, dia 6 mm) are used in H3PO4 medium. Cyclic vottammograms are obtained in the oxygen evolution region and oxygen reduction region. The exchange current density of the catalyst for oxygen evolution and reduction ir reported for different catalyst loadings.
