Preparation and Characterization of the Highly Regular Nitrogen Doped Anatase TiO₂ Nanotube

Abstract:

Nitrogen-doped TiO₂ nanotubes (N-TNTs) were fabricated on the titanium foil by anodic oxidation and followed by annealing at NH₃ environment. Highly ordered nanotubes, roughly 150 nm in the diameter and 20 μm in the length, were synthesized on the titanium foil. By controlling oxidation voltage, the thick TiO₂ nanotubes were peeled off from the titanium substrate. In one step annealing at NH₃ environment, nitrogen replaced oxygen and doped into TiO₂, but anatase phase was formed.
