Study of the electrocatalysis of oxidation reactions of organic fuels on ordered intermetallic phases Pt-M

Abstract

Based on previous studies on materials obtained by the deposition of metallic ions on platinum surface and also preliminary studies of oxidation of organics in ordered intermetallic phases of BiPt, the aim of this project is to study the electrocatalysis of the oxidation reaction of methanol, ethanol, ethylene glycol and the corresponding carboxylic acid derivatives on the BiPt, SnPt, MoPt and MnPt phases, in acid medium. The reactions will be studied through techniques of cyclic voltammetry, rotating disk electrode, differential electrochemical mass spectroscopy and spectroscopy in the infrared region. The kinetic parameters and the mechanistic information obtained will be interpreted with a view to establishing a clearer relationship between the characteristics of the electrodic surface and the electrocatalytic activity in the respective reactions.
