Abstract: 
The synthesis of titanium(IV) oxide nanopowders modified by sulfur with the help of sol-gel method has been described. The structure of surface layers has been investigated using X-ray diffraction analysis, a scanning electron microscopy, IR-spectroscopy and X-ray photoelectron spectroscopy. The possible mechanism of powders surface modification by sulfur has been shown, as well as the dependence of specific surface on sulfur content.
