Preparation and Electrocatalytic Oxidation Characteristics of Ethanol on Pd/C Catalyst

摘要

Nanoparticle Pd/C catalyst was prepared by a microwave-assisted polyol process (MAPP). Ethylene glycol was used as reducing agent. The Pd/C catalyst was characterized by transmission electron microscopy (TEM) and X-ray diffractometry (XRD). The catalyst was spherical and homogeneously dispersed on activated carbon carrier with particle size about 5-7nm. Electrochemical analysis results shows, Pd/C catalyst exhibits higher reactivity toward electrocatalytic oxidation ethanol in alkaline electrolyte, compared to commercial Pd/C (Johnson Matthey Co.).
