摘要：
We fabricated highly ordered arrays of TiO2 nano-tubes(NT) by anodizing Ti foil in ethylene glycol and NH4F electrolyte. The same time, we studied the effects by changing anodization parameters including the content in electrolyte, voltage and reaction time. Using scanning electron microscopy(SEM) and X-ray diffraction (XRD) we analyzed the nanostructure and morphology of the TiO2 nano-tubes. And we discussed the mechanism of the NT array formation in reference with the current-time curve. The results showed that TiO2 nano-tubes diameters and morphologies changed by altering of varying anodization parameters. The crystal type can change after the TiO2 nano-tubes were annealed at different temperatures.
