Titania (TiO2) nanotube is considered a very important material due to its promising applications in many fields ranging from energy harvesting to sensors and photocatalytic applications. TiO2 nanotubes were grown electrochemically in Plexiglas cell, the Ti foils (99.96%) serves as anode and platinum foil as cathode while the electrolyte was ethylene glycol containing (0.5%) NH4F and (4%) de-ionized water at 20?¢????¦C for one hour. The effect of anodizing voltages at the range 10 to100v is studied by extensive current / voltage plots and microstructure examination using SEM, and AFM techniques. All potentials were led to highly ordered nanotubes but they have different micrographic parameters; tube length, tube diameter and tube wall thickness, a role these parameters with the values of anodizing potentials are investigated.
