Fe-N-doped TiO 2 , Fe-S-doped TiO 2 and Fe-N-S-doped TiO 2 were prepared with Fe doping peroxotitanium complex (Fe-PTC) as precursor in aqueous solution by a low-temperature process. The structure and properties of catalysts were characterized by XRD, FT-IR, XPS, TEM and UV–Vis respectively. Fe-N-doped TiO 2 , Fe-S-doped TiO 2 and Fe-N-S-doped TiO 2 all belong to anatase phase. The UV–Vis spectra of doped TiO 2 exhibited a red shift to 535nm and stronger absorption than that of pure TiO 2 in visible region. The pure TiO 2 displays bullet-like morphology with widths of about 20nm and Fe-N-S-doped TiO 2 consisted of irregular particles with diameters about 5–10nm. The doped samples all exhibited higher photocatalytic activity in the degradation of 2,4,6-trinitotoluene (TNT) in red water compared to pure TiO 2 . Fe-N-S-doped TiO 2 presented the highest photocatalytic activity and degraded about 91.5% 2,4,6-trinitotoluene within 12h under visible light irradiation. Structural characterization and property analysis results revealed that the co-doping of Fe-N, Fe-S and Fe-N-S remarkably altered the crystal specific surface area, microstructure, as well as the photocatalytic activity.
