Visible light induced wetting of nanostructured N–F co-doped titania films

Abstract

Nitrogen and fluorine co-doped TiO2 films have been prepared by dip coating of a modified titania sol–gel based on a nitrogen precursor and a nonionic fluorosurfactant as pore template and fluorine source. The modified NF–TiO2 films absorb in the visible spectral range, between 400–510 nm and undergo reversible hydrophilic conversion under visible light to a final contact angle of 8°, in contrast to the UV limited optical response of their undoped anatase TiO2 analogues. The phenomenon takes place at a rate slower than the corresponding one observed for the UV stimulated superhydrophilic effect. The wetting response of the N–F doped TiO2 films correlates well with the variation of their optical properties and surface morphological characteristics and most importantly with their photocatalytic activity, rendering these materials very promising for self-cleaning applications under visible light.
