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.559-562openAccesselectrocatalystsplatinumtincarbonboron hydridesreductionnitric acidethanoloxidationx-ray diffractionamperometrydirect ethanol fuel cellsArtigo de periódico1175https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0002-9287-6071
