A comparative study on the morphological features of highly ordered titania nanotube arrays prepared via galvanostatic and potentiostatic modes

The formation of highly ordered, vertically aligned titania (TiO2) nanotubes (NTs) via the cost effective galvanostatic and potentiostatic anodization techniques is reported. In both the approaches, the variation of water content in terms of fresh and used ethylene glycol based electrolyte has been considered as a significant parameter to genuinely investigate each of the anodization modes. Noteworthy differences and influences were clearly observed in terms of anodization kinetics and the resulting tubular morphology, such as architecture and arrangement during the development TiO2 NTs arrays. The as-synthesized samples were characterized by powder X-ray diffraction (XRD), Field emission scanning electron microscope (FESEM) and Energy dispersive X-ray analysis (EDX). (C) 2014 Elsevier B.V.
