Highly ordered arrays of Titanium dioxide (Ti0₂) nanotubes were synthesized from Titanium foil substrate using the electrochemical anodization process in an etching solution consisting of Ammonium Fluoride (NH₄F), Ethylene Glycol and nanopure water. The topologies (lengths and diameter) of the synthesized TiO₂ were found to be governed by two main process parameters, applied voltage and etching solution concentration. The applied voltage was varied between 55V DC to 65V DC. The concentration of the etching solution was altered by varying the weight % of the NH₄F between 0.3 to 0.5%. By varying the process parameters, TiO₂ nanotubes with diameters between 176 to 227 nanometers and lengths between 74 and 103 nanometers were obtained.
