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.
