Electro-Oxidation of Methanol on TiO2 Nanotube Supported PlatinumElectr odes

TiO2 nanotubes have been synthesized using anodic alumina membrane as template. Highly dispersed<br>platinum nanoparticles have been supported on the TiO2 nanotube. The supported system<br>has been characterized by electron microscopy and electrochemical analysis. SEM image shows<br>that the nanotubes are well aligned and the TEM image shows that the Pt particles are uniformly<br>distributed over the TiO2 nanotube support. A homogeneous structure in the composite nanomaterials<br>is indicated by XRD analysis. The electrocatalytic activity ofthe platinum catalyst supported on<br>TiO2 nanotubes for methanol oxidation is found to be better than that of the standard commercial<br>E-TEK catalyst.
