Abstract

In this study, we investigate the physical properties and photocatalytic activities of TiO₂ thin films doped with low valence (Fe ³⁺, Co²⁺, and Ni²⁺) and high valence (Mo ⁵⁺, Nb⁵⁺, and W⁶⁺) cations. Clear difference in results from various analytical tools between groups was identified. The presence of different oxidation states and a higher degree of crystallinity in the high valence cation doped-TiO₂ thin films seemed beneficial in terms of the transfer and separation of photo-generated electrons and holes in the TiO₂ medium and on the surface, resulting in higher photocatalytic conversion of trichloroetylene.
