Abstract

Nanostructuring and morphological engineering are the two important aspects of the control of the performance of functional materials. In the present work, we report on the fabrication of high aspect discrete TiO2 nanotubes possessing two or multi-legs via electrochemical anodization of titanium foil. The effect of applied voltage and anodization time with appropriate optimization of electrolyte containing (NH4) HF2 in diethylene glycol-based electrolyte were investigated. Scanning electron microscopy was employed to examine the morphology of the synthesized TiO2 nanotubes. We observed that prolonged anodization times from 2 hrs to 6 hours, results in the formation of dense and high aspect nanotubes with improved lengths compared to the sample synthesized with 2 hours of anodization time.
