Abstract

A novel PdNi/TiO₂ electrocatalyst for methanol oxidation is fabricated using spherical TiO₂ nanoparticles as support. The structural and electrochemical properties of the PdNi/TiO₂ catalyst are characterized by XRD, TEM and electrochemical analysis. The cyclic voltammograms of PdNi/TiO₂ catalyst show that there is a large methanol oxidation peak in about 0.882V that is much bigger than that of the commercial PtRu/C catalyst in 0.7V. The composite TiO₂ material has high catalytic activity without UV light illumination. The electrocatalytic activity and anti-poisoning capability of the PdNi/TiO₂ catalyst are promising, which may become a potential candidate for direct methanol fuel cell.
