Abstract

Abstract: Iodine doped nanocrystalline TiO₂ photocatalyst was prepared by sol-gel method. The results show that crystallinity of anatase was improved upon iodine doping, and iodine not only suppressed phase transition anatase to rutile, but also exhibited an absorption in the wave length range of 400—550 nm. The photocatalytic activity of I-doped TiO₂ photocatalysts(500 ℃) exceeded that of pure TiO₂ photocatalyst prepared by the same method when the molar ratio of HIO₃ to Ti was kept in the range of 0.05—0.20.
