The topography of Titanium nanotube diameter and length had been affected without usage of magnetic stirrer by applying at three different DC voltage. In this study, we had synthesized Titanium nanotube arrays by electrochemical anodization of Ti foil by direct current (D.C.). Ethylene glycol and ammonium fluoride electrolyte was used to study the development of nanotubes above atmospheric temperature with varying D.C voltages. Then the Ti foil was annealed to form anatase for one hour in a muffle furnace. High Resolution Scanning electron microscopy, UV–vis spectroscopy and X-ray diffraction were used to characterize the Ti thin film nanotubes anode. HRSEM revealed the topography of the titanium nanotubes anode. At 60 V to 30 V, the mean tube diameter was 57.34 nm. At 50 V to 25 V, the mean tube diameter was 97.64 nm. At 40 V to 20 V, the mean tube diameter was 122.45 nm.</span>
