N2 - 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.
