Resumo
PtSnCu/C electrocatalyst with Pt:Sn:Cu atomic ratio of 50:30:20 was prepared by
borohydride reduction and the obtained material was further treated with nitric acid. The
obtained material was characterized by EDX and XRD and tested for ethanol electrooxidation in acid medium using chronoamperometry. The X-ray diffractogram of assynthesized PtSnCu/C electrocatalyst showed typical face-centered cubic (fcc) structure
of Pt alloy and after acid treatment it was observed that the Pt (fcc) structure was
preserved. PtSnCu/C electrocatalyst acid-treated was more active for ethanol electrooxidation than as-synthesized PtSnCu/C and PtSn/C electrocatalyts.
