(C, N and S) co-doping in TH-TiO2 samples can promote the formation of the pure anatase structure.
(C, N and S) atoms were successfully co-doped into the nanostructures of TH-TiO2 samples.
The band gap energy of TH-TiO2 samples reduced after (C, N and S) co-doping.
(C, N and S) co-doped TiO2 samples were effective for the photocatalytic reduction of Cr(VI) under visible light irradiation.
