A study of the growth mechanism of large-diameter double-wall TiO₂ nanotube arrays fabricated by high voltage anodization.

ABSTRACT:

Background

Research on the growth mechanism of titanium dioxide (TiO₂) nanotube arrays fabricated by anodic oxidation is essential to achieve artificial control of the microstructure and to expand their applications. In our previous work, we reported the preparation of highly ordered large-diameter double-wall TiO₂ nanotube arrays prepared by high voltage anodization.

Methods

In this paper, we observed and analyzed the initial growth process of large-diameter double-wall TiO₂ nanotube arrays anodized at 120 V in ethylene glycol electrolyte containing aluminum fluoride (NH₄F) and water (H₂O), such as the evolution of surface and cross-sectional morphologies, the influence of current density on growth rate, the transition
