The electrochemical surface area (ESA) values have been determined from the charge in-volved in the oxidation of adsorbed hydrogen in the cyclic voltammograms in 1.0 M H<sub>2</sub>SO<sub>4</sub> solution, assuming a value of 210 µC/cm<sup>2</sup> for a monolayer coverage and compared with the values, determined by the XRD technique. ESA value of 101.0 m<sup>2</sup>/g has been obtained for a 2 wt% Pt catalyst on carbon, which decreased to a value of 77.6 m<sup>2</sup>/g when the Pt loading is increased to 10 wt%. The calculated Crystallite size values have also been found to be in good agreement with the values determined by XRD technique for the above catalysts.</span> |
