Excellent durability of substoichiometric titanium oxide as a catalyst support for Pd in alkaline direct ethanol fuel cells / Son Truong Nguyen in Industrial & engineering chemistry research, Vol. 51 N° 30 (Août 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 30 (Août 2012) . - pp. 9966-9972 Titre : Excellent durability of substoichiometric titanium oxide as a catalyst support for Pd in alkaline direct ethanol fuel cells Type de document : texte imprimé Auteurs : Son Truong Nguyen, Auteur ; Jong-Min Lee, Auteur ; Yanhui Yang, Auteur Année de publication : 2012 Article en page(s) : pp. 9966-9972 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Fuel  cell  Catalyst  support  Titanium  oxide  Durability Résumé : In this study, substoichiometric titanium oxide, TinO2n―1, was compared with carbon black and TiO2 in the role of catalyst supports for Pd in alkaline direct ethanol fuel cell. 10%Pd/C, 10% Pd/commercial TiO2 and 10%Pd/TinO2n―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 TinO2n―1 with holding potential and multiscan tests in N2-purged 1 M KOH solution. Among the three catalysts, Pd/TinO2n―1 showed the best activity and stability for ethanol electrooxidation in alkaline media.
