Abstract
A new catalyst, platinum nanostructure electrodeposited on tantalum substrate (Pt/Ta), was prepared. The morphology and surface analysis of Pt/Ta electrodes were investigated using SEM and EDX, respectively. Electrochemical characteristics of ethanol oxidation on Pt/Ta electrodes were investigated via cyclic voltammetric in acidic solutions. The results were compared to those at a smooth platinum electrode. It was found that the electro-catalytic oxidation of ethanol on the Pt/Ta electrode increases the rate of ethanol electro-oxidation several times larger than a smooth platinum electrode and confirmed the better electro-catalytic activity and stability of Pt/Ta electrodes.
