Highly ordered TiO2 nanotubes (TiO2-NTs) were grown from Ti substrate. More load sites for specified metal were provided by this nanotube structure. TiO2-NTs/Pt electrodes for electrocatalytic oxidation were prepared through hydrothermal reaction between TiO2 nanotubes and H2PtCl6·6H2O. Characterization of the electrodes by scanning electron microscope (SEM) and X-ray diffraction (XRD) illustrates that Pt nanoparticles with an average size of 20-30 nm are dispersed on the surface or in the pore of TiO2 nanotube. The results of cyclic voltammetry (CV) show that in the system without dyes the current density at the oxidation peak of 0.13 V of TiO2-NTs/Pt electrodes is 9 times greater than that of Pt bulk electrode; while in the system with dyes, the oxidation peak current density of the TiO2-NTs/Pt electrodes to acid scarlet GR is 4.2 times that of Pt bulk electrodes. The results of degradation to acid scarlet GR show that TiO2-NTs/Pt electrodes possess high catalytic activity and high-efficiency degradation ability
