Resumo
PtSn/CeO2–C electrocatalyst and PtSn/Rh-C were prepared in a two step. In the first step a Carbon
Vulcan XC72 + 15%CeO2 and Vulcan XC72 + 15%Rh supports were prepared using a modified
polymeric precursor method under controlled synthesis conditions. In the second step PtSn
electrocatalyst was prepared by an alcohol-reduction process using ethylene glycol as solvent and
reducing agent and supported on Vulcan XC72 + 15%CeO2 and Vulcan XC72 + 15%Rh. The obtained
electrocatalysts were characterized by XRD and cyclic voltammetry. The electro-oxidation of ethanol
was studied by cyclic voltammetry and chronoamperometry at room temperature. PtSn(50:50)/CeO2–C
electrocatalyst showed a significant increase of performance for ethanol oxidation compared to PtSn/C
catalyst and others electrocatalysts prepared.
