Abstract
Fabrication of PF-codoped TiO2 nanotubes was carried out using a one-step electrochemical anodization process by tailoring the composition of the electrolyte with the aim of PF-codoping to extend the optical absorption of TiO2 to the visible-light region. The as-prepared PF-codoped TiO2 nanotubes were characterized by SEM, XPS, and UV-vis diffuse reflectance absorption spectra (DRS). The results showed that the tube diameter of the nanotubes was approximately 100Â nm and the tube length was approximately 510Â nm. The phosphorus and fluorine were successfully doped into TiO2 nanotubes, as evidenced by XPS. Moreover, the PF-codoped samples displayed remarkably strong visible-light response.
