Abstract

In this study, substoichiometric titanium oxide, Ti _nO _2n-1, was compared with carbon black and TiO ₂ in the role of catalyst supports for Pd in alkaline direct ethanol fuel cell. 10%Pd/C, 10% Pd/commercial TiO ₂ and 10%Pd/Ti _nO _2n-1 catalysts were successfully prepared by a polyol method. The supports and electrocatalysts were characterized by X-ray diffraction (XRD), nitrogen adsorption, electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), linear sweep voltammetry (LSV), and chronoamperometry (CA) techniques. Excellent durability was found for Ti _nO _2n-1 with holding potential and multiscan tests in N ₂-purged 1 M KOH solution. Among the three catalysts, Pd/Ti _nO _2n-1 showed the best activity and stability for ethanol electrooxidation in alkaline media.
