Abstract

A novel PdAg/TiO₂ nanotube electrocatalyst was successfully prepared by the surface reductive deposition method and displacement reaction using TiO₂ nanotube as support. The structural and electrochemical performances of the PdAg/TiO₂ nanotube catalyst were characterized by XRD, TEM and electrochemical analysis. The PdAg/TiO₂ nanotube electrocatalyst has shown promising catalytic activity for methanol electro-oxidation. The methanol oxidation mechanism of the PdAg/TiO₂ nanotube catalyst mainly results from the photocatalytic mechanism of composite TiO₂ material that has high catalytic activity without ultraviolet (UV) light illumination. The PdAg/TiO₂ nanotube catalyst might become a promising candidate for direct methanol fuel cell.
