摘要：
Sulfur-doped titanium dioxide (S-TiO2) hollow spheres were prepared by the reaction of tetrabutyl titanate and thiourea as the main raw material with polystyrene-hydroxyethyl acrylate copolymer (P (St-HEA)) microspheres templates. The morphology, crystal type and state of elemental sulfur doping of S-TiO2 hollow spheres was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Study the catalytic properties of S-TiO2 hollow spheres using methanal solution simulated wastewater. The results showed that TiO2 hollow spheres were obtained by removing P (St-HEA) microspheres template successfully, the particle size and morphology of TiO2 hollow spheres are little effected by sulfur-doping, the crystallite dimension of TiO2 hollow spheres diminished and the crystal shape of TiO2 hollow spheres was changed from pure anatase into anatase/rutile. Sulphur was present in the form of S4+ which substitutes Ti4+ in the titania lattice, forming Ti1-xSxO2 solid solution. The performance of photocatalysis of doped sample was superior to the pure TiO2 hollow spheres, while they both preceded TiO2 powder. The catalytic efficiency of synthesized photocatalyst was 60% for degrading methanal under UV-light. © 2015, Journal of Functional Materials. All right reserved.
