Electrochemical Study of Palladium-Based Bimetallic Electrocatalysts Supported on Carbon Vulcan XC72R for Methanol Electro-Oxidation in Alkaline Media

Abstract

Palladium-based electrocatalysts supported on carbon Vulcan XC72R were synthesized by combustion to step up the methanol electro-oxidation reaction (MER) in alkaline media and physico-chemically characterized by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) to establish composition, crystallite and particle sizes, respectively. The catalytic activity was evaluated by electrochemical techniques, namely, cyclic voltammetry (CV) and chronoamperometry (CA) using the well-known electrochemical parameter: steady state anodic current density (j ss).
