Resumo
Pt rare earth–C electrocatalysts (rare earth = La,
Ce, Pr, Nd, Sm, Tb, Dy, Ho, Er, Tm, and Lu) were prepared
by an alcohol reduction process using ethylene glycol as
reduction agent and solvent and Vulcan XC 72 as support.
The electrocatalysts were characterized by energy-dispersive X-ray analysis, X-ray diffraction (XRD), and cyclic
voltammetry. The electrooxidation of ethanol was studied
in acid medium by cyclic voltammetry and chronoamperometry using thin porous coating technique. The XRD
patterns indicate that all electrocatalysts present the facecentered cubic structure of Pt and the presence of rare earth
hydroxides. All electrocatalysts prepared by this methodology showed superior performance for ethanol electrooxidation at room temperature compared to Pt–C.
