The performance of Pt nanoparticles supported on Sb(2)O(5 center dot)Sno(2), on carbon and on physical mixtures of Sb2O5 center dot SnO2 and carbon for ethanol electro-oxidation
Pt nanoparticles were supported on Sb2O5 center dot SnO2 (ATO), on carbon and on physical mixtures of ATO and carbon by an alcohol-reduction process using ethylene glycol as reducing agent. The obtained materials were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Their performance for ethanol oxidation was investigated at room temperature by chronoamperometry and in a direct ethanol fuel cell (DEFC) at 100 degrees C. Pt nanoparticles supported on a physical mixture of ATO and carbon showed a significant increase of performance for ethanol oxidation compared to Pt nanoparticles supported on ATO or on carbon.
