摘要：
Platinum(Pt) nanoflower structure was electrodeposited on the surface of the aligned TiO2 nanotube, which was fabricated by anodic oxidation on titanium samples. The obtained electrode was characterized by XRD and SEM. The experiment results show that Pt is dispersed on the TiO2 nanotubes in the shape of nanoflowers, particle size is 25. 6 nm based on the calculations of XRD. Compared with pure Pt and clean TiO2 nanotube arrays, the hybrid electrodes' electrocatalytic activity for methanol oxidation has been greatly improved. The oxidation current densities on Pt-TiO2 nanotubes electrode are 40 times higher than that of pure platinum electrode. The hybrid electrode shows promising applications in many fields, such as direct methanol fuel cell, treatment of polluted water and so on.
