Paper Title:
Preparation and Optical Properties of TiO2 Nanotube Arrays by Anodic Oxidation Method
  Abstract

Titania nanotube arrays were fabricated by anodic oxidation of a pure titanium foil. The morphology, structure and optical properties of the nanotube arrays were characterized by SEM, XRD and UV-Vis spectrum. The effect of anodic oxidation parameters on the morphology was investigated. The growth mechanism of the titania nanotube arrays was discussed. The results show that the vertical oriented TiO2 nanotube arrays can be obtained at 20V for 60min in 0.5wt%HF+1mol/L H3PO4 solution. The aperture size of nanotube is 60nm~80nm and the thickness of tube wall is about 10nm. The spectral absorptivity of TiO2 nanotube arrays membrane calcined at 600°C towards ultravlolet light 349.7nm and visible light 443.9nm was relatively higher. It is also found that the crystal structure is greatly affected by calcining temperature.
