The electrocatalysts were characterized by energy dispersive X-ray analysis (EDX), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The electro-oxidation of methanol was studied in acid medium by cyclic voltammetry and chronoamperometry using thin porous coating technique. The XRD patterns indicate that all electrocatalysts present the face-centered cubic (fcc) structure of Pt and the presence of Rare Earth hydroxides. PtEr/C, PtTb/C, PtLa/C, PtDy/C and PtNd/C electrocatalysts prepared by this methodology showed superior performance for methanol electro-oxidation at room temperature compared to Pt/C.288-291openAccesselectrocatalystsplatinumrare earthsalcohol fuel cellsreductionglycolssolventsmethanoloxidationvoltametryamperometryArtigo de periódico1-247610.1016/j.jallcom.2008.08.073https://orcid.org/0000-0003-0105-6519https://orcid.org/0000-0002-7011-8261https://orcid.org/0000-0002-9287-6071
