Electro-Oxidation of Methanol on TiO2 Nanotube Supported PlatinumElectr odes

TiO2 nanotubes have been synthesized using anodic alumina membrane as template. Highly dispersedplatinum nanoparticles have been supported on the TiO2 nanotube. The supported systemhas been characterized by electron microscopy and electrochemical analysis. SEM image showsthat the nanotubes are well aligned and the TEM image shows that the Pt particles are uniformlydistributed over the TiO2 nanotube support. A homogeneous structure in the composite nanomaterialsis indicated by XRD analysis. The electrocatalytic activity ofthe platinum catalyst supported onTiO2 nanotubes for methanol oxidation is found to be better than that of the standard commercialE-TEK catalyst.
