Abstract
In this work, the influence of two carbon supports on the electrocatalytic performance of Pd-Au materials for the glycerol oxidation reaction in KOH electrolyte is investigated. Pd-Au/OMC and Pd-Au/MWCNT have been synthesized by the polyol reduction method. The catalysts have been characterized by XRD, EDS and electrochemical techniques. The results show the influence of the carbon support on the catalytic activity of the Pd-Au anodes. Such effect could be attributed to the fact that the relatively large pores in the OMC support facilitate the mass transfer process, allowing a high concentration of exposed active sites that participate in the reaction.
