Cyclic Voltammetric Preparation of Palladium Nanoparticles for Ethanol Oxidation Reaction

By simple cyclic voltammetry of a PdO-coated glassy carbon (GC) electrode for a few cycles with the potential swept from -1.0 to -1.2 V versus saturated calomel electrode in an alkaline solution containing ethanol, a Pd particle modified GC electrode was fabricated. It showed satisfactory catalysis toward the ethanol oxidation reaction.
