The TiO2 nanostructure support consists of backbones and branches of a rutile phase forming a 3-dimensional structure with high specific surface area. The Pt catalysts on the TiO2 nanostructure supports exhibit much improved electrocatalytic activity and stability toward methanol electrooxidation in comparison with conventional Pt/C.
