Photocatalytic <TEX>$TiO_2$</TEX> films were prepared by anodic oxidation at 180 V and their structural difference caused by oxidation conditions was studies. The microstructure of <TEX>$TiO_2$</TEX> films in <TEX>$H_2SO_4$</TEX> and <TEX>$H_2SO_4/H_2O_2$</TEX> solution was mixed type of rutile and anatase. However, the <TEX>$TiO_2$</TEX> layer formed in <TEX>$H_2SO_4/H_3PO_4$</TEX> and <TEX>$H_2SO_4/H_3PO_4/H_2O_2$</TEX> mixture was mostly anatase type. All <TEX>$TiO_2$</TEX> 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.
