Preparation and Microstructure of Titania (TiO₂) Nanotube Arrays by Anodization Method

Abstract:

TiO₂ nanotube arrays were successfully synthesized by the anodization method of Ti foils in electrolyte containing the mixtures of ethylene glycol (EG), ammonium fluoride (0.3 wt % NH₄F) and deionized water (2 Vol % H₂O). A constant dc power supply at 50 V was used anodization process with different anodizing times. The resultant samples were annealed at 450 °C for 2 h. TiO₂nanotube arrays were studied by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The prepared TiO₂NTs has diameter in 50-200 nm. The minimum of diameter TiO₂nanotube arrays was approximately 50 nm for 1 h of anodization process.
