Recent advances in synthesis, modification, and applications of tio2 nanotube arrays by electrochemical anodization

Abstract

Titania nanotube arrays (TNAs) as one of the hottest metal oxide nanomaterials has a unique one-dimensional highly ordered array structure, good mechanical and chemical stability, as well as excellent anticorrosion, biocompatible, and photocatalytic performance. It has been controllably synthesized by a simple electrochemical anodic oxidation in electrolytes containing small amounts of fluoric ions. In combination with our last research work, in this chapter, we review the recent advances of the new research achievements of TNAs on the preparation techniques, formation mechanism, and modification. In addition, we will review the potential and significant applications in the photocatalytic pollutant degradation, solar cells, hydrogen generation, biomedical implant, wetting template, and other aspects. Finally, the existing problems and further prospects of this renascent and rapidly developing field are also briefly addressed and discussed.
