Abstract

The effect of the repeated UV illumination on the photo-induced wettability conversion of TiO2 surface was investigated using rutile single crystal. The hydrophilicizing rate was increased by the repeated UV illumination andthis effect was more remarkable on (001) than (110) surface. This crystal plane dependence can be attributed to the differences of the efficiencies of oxygen vacancy creation and the degrees of resultant structural distortion between these two surfaces. These data suggest that the hydrophilicizing process of TiO2 is a kind of photo-corrosion process occurring at the surface. (C) 2001 Published by Elsevier Science B.V.
