Study on preparation of TiO_2 nanotube arrays by anodizing processes

TiO2 nanotube arrays were fabricated by anodic oxidation on a pure titanium in HF aqueous solution.It was studied that the influences of the parameters for the preparation of titania nanotube arrays on the micrograph of the material,such as anodizing potential,concentration and temperature of the electrolyte.The microstructures and morphologies of the TiO2 nanotubes were investigated by scanning electron microscopy(SEM) and X-ray Diffraction(XRD).The results showed that TiO2 nanotubes diameters and morphologies changed by altering of anodizing potential,concentration and temperature of the electrolyte.
