Abstract

We demonstrate here for the first time the fabrication of a novel morphology of rutileTiO₂ tapered nanotubes with rectangular cross-sections via a facile hydrothermal method using TiO₂nanorod as the precursor. A plausible anisotropic corrosion mechanism for the formation of TiO₂ nanotubes is also proposed.
