S-TiO 2 with enhanced visible-light photocatalytic activity derived from TiS 2 in deionized water
Source abstract
Abstract
Abstract Sulfur-doped anatase TiO 2 nanoparticles with sulfur atoms occupying oxygen sites were realized by low-temperature hydrothermal oxidation of titanium disulfide (TiS 2 ) with deionized water as the solvent. S doping can effectively narrow the bandgap of TiO 2 due to the fact that S 3 p 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-TiO 2 oxidized at high temperature. The low-temperature hydrothermal oxidation of TiS 2 in pH neutral solvent is an environmental-friendly method to obtain S-TiO 2 with high photocatalytic activity, which can be extended to other nonmetal doping of TiO 2 or other semiconductors for bandgap engineering.
