Abstract

A series of highly ordered N—F-codoped TiO2 nanotubes were synthesized with a simple template technique and the obtained samples were detected by FE-SEM and XPS. The UV-Vis absorption spectrum showed that after N—F-codoping, TiO2 nanotubes had a new absorption band at 425 nm, leading to a photoresponse in the visible region. These modified nanotubes showed a significant visible-induced photocatalytic activity for the degradation of methylene blue in aqueous solution.
