Abstract

Sulfur-doped anatase TiO₂ nanoparticles with sulfur atoms occupying oxygen sites were realized by low-temperature hydrothermal oxidation of titanium disulfide (TiS₂) with deionized water as the solvent. S doping can effectively narrow the bandgap of TiO₂ due to the fact that S 3p level is higher than O 2p orbital. The large surface area caused by this doping method induces higher photocatalytic activity in the visible regime compared with S-TiO₂ oxidized at high temperature. The low-temperature hydrothermal oxidation of TiS₂ in pH neutral solvent is an environmental-friendly method to obtain S-TiO₂ with high photocatalytic activity, which can be extended to other nonmetal doping of TiO₂ or other semiconductors for bandgap engineering.
