Progress of Studies on Fabrication of TiO2 Nanotube Arrays on Ti or Ti Alloys by Anodization
Abstract:
This paper gives an overall review of TiO2 nanotube arrays synthesized on titanium and its alloys substrates by anodization. The highly ordered nanotubes are fabricated by electrochemical anodization in electrolyte containing fluoride ion. During the anodization process, the electrochemical conditions such as the electrolyte, applied voltage, anodization time, temperature and alloy substrates are analyzed in detail. Anodization of titanium alloy is a simple and effect method to dope element into TiO2 nanotube which shows much higher improvement in photocatalytic and solar energy conversion than pure TiO2 nanotube arrays. In addition, we review the forming mechanism and modification. Furthermore, TiO2 nanotube arrays have great application for dye-sensitized solar cells, water splitting and biomedical and other aspects.
