Photocatalytic treatment of 2,4,6-trinitotoluene in red water by multi-doped TiO2 with enhanced visible light photocatalytic activity

Pure TiO2, Fe-N-doped TiO2, Fe-S-doped TiO2 and Fe-N-S-doped TiO2 were successfully prepared. The multi-doped TiO2 shown photodegradation of TNT in red water under visible-light irradiation.
