Abstract

Direct alcohol fuel cells stand out as a good alternative to fossil fuels in terms of energy efficiency. In this study, electrochemical synthesis of CeO2 nanostructures was performed on the surfaces of pencil graphite electrodes (PGEs). The prepared CeO2 nanostructures were characterized using various techniques, and their surfaces were then decorated with Pd nanoparticles via electrochemical methods. Pd nanoparticles decorated-CeO2 (Pd@CeO2) nanostructures were characterized by Field emission scanning electron microscopy (FESEM), Energy dispersive spectroscopy (EDS), Electrochemical impedance spectroscopy (EIS) technique. The activity of Pd nanoparticle-added CeO2 nanostructures in the electro-oxidation of ethanol was investigated, and an approximately 16-fold increase in the oxidation current density of ethanol was observed compared to CeO2.
