High photocatalytic activity of Fe₂O₃/TiO₂ nanocomposites prepared by photodeposition for degradation of 2,4-dichlorophenoxyacetic acid.

ABSTRACT: Two series of Fe₂O₃/TiO₂ samples were prepared via impregnation and photodeposition methods. The effect of preparation method on the properties and performance of Fe₂O₃/TiO₂ for photocatalytic degradation of 2,4-dichlorophenoxyacetic acid (2,4-D) under UV light irradiation was examined. The Fe₂O₃/TiO₂ nanocomposites prepared by impregnation showed lower activity than the unmodified TiO₂, mainly due to lower specific surface area caused by heat treatment. On the other hand, the Fe₂O₃/TiO₂ nanocomposites prepared by photodeposition showed higher photocatalytic activity than the unmodified TiO₂. Three times higher photocatalytic activity was
