Abstract

Photocatalytic $TiO_2$ films were prepared by anodic oxidation at 180 V and their structural difference caused by oxidation conditions was studies. The microstructure of $TiO_2$ films in $H_2SO_4$ and $H_2SO_4/H_2O_2$ solution was mixed type of rutile and anatase. However, the $TiO_2$ layer formed in $H_2SO_4/H_3PO_4$ and $H_2SO_4/H_3PO_4/H_2O_2$ mixture was mostly anatase type. All $TiO_2$ films prepared by anodic oxidation exhibited photocatalytic properties. The photocatalytic degradation of aniline blue was first order reaction with similar rate constants at all oxidative conditions examined in this work.
