Abstract

TiO₂ nanotube arrays have an important role on the application of solar cells, air purification, dust water cleaning and hydrogen fuel generation. Highly aligned titanium oxide (TiO₂) nanotube (NT) arrays have been grown on titanium sheet by using a self organized anodic oxidation method at different potentials (32 to 52V) in a NH₄F and ethylene glycol based electrolyte. The temperature has been maintained to 25°C. The formation and growth mechanism of TiO₂ NTs have been discussed with proposed experimental model. The structural property of TiO₂ NTs is investigated by using energy dispersive spectrophotometer. The surface morphology has been confirmed by scanning electron microscopy.
