The aim of this work is to fabricate highly aligned titanium oxide (TiO2) nanotube (NT) arrays by using a self organized anodic oxidation method with different ammonium fluoride (NH4F) concentrations in ethylene glycol based electrolyte. The formation and growth mechanism of TiO2 NTs have been discussed and observed the effect of changing fluoride (F) ions on NTs. The current transient profile of...
Highly-ordered, densely-packed, hexagonal TiO2 nanotubes were synthesized in a single-step anodization of Ti foil using a constant dc potential of 60 V. The synthesized nanotubes exhibit a bamboo-like structure, with rings formed along the length. X-ray diffraction reveals the as-grown nanotubes to be amorphous, which upon annealing at 723 K changes to a dominantly crystalline anatase phase. A high...
