TiO2 was doped with various types of rst row transition metals towards the degradation of dichloromethane, chloroform, carbon tetrachloride and a mixture of carbon tetrachloride and chloroform.Zn2+/Fe3+/TiO2 photocatalyst with the ratio of 0.0005: 0.0005: 1 was revealed as the best catalyst inthis study. 41.05% of dichloromethane, 49.45% of chloroform and 37.84% of carbon tetrachloride weredegraded by this catalyst in the presence of UV light (6 W, 354 nm), irradiated for 90 minutes, and oxidizedVOCs gases were analyzed using GC-FID. In this study, the new species of CHCl+ 2 , CH2Cl+, CCl+2 and OCl+. CHCl+ 2 was detected to form from the photocatalytic degradation of chloroform while some new fragments, such as OCl+, CHCl+ 2 and CH2Cl+, are observed during the photocatalytic degradation of carbon tetrachloride.
