Abstract

In this work different aspects referring to the Oxidation Reaction of Ethanol (ORE) will be analyzed. In the first instance the catalytic reaction in function of the crystallographic orientation of platinum will be evaluated. Next Pt electrodes modified by the inclusion of a second metal will be investigated. Electrochemical studies will be undertaken coupled to spectroscopic techniques. In a later phase, dispersed catalysts will be prepared based on compositions that present the best catalytic activity regarding ORE. The studies should end with the physical and electrochemical characterization of electrocatalysts prepared in identical conditions to those used in fuel cells. (AU)
