A study was carried out on the change in the composition of a Ti-Mo-W catalyst depending on the conditions for their treatment by H/sub 2/S-SO/sub 2/ and H/sub 2/S-O/sub 2/ gas mixtures, which serve as models for the technological gases in Klaus apparatuses and the direct catalytic oxidation of H/sub 2/S. X-ray photoelectron spectroscopy was used to establish the formation of sulfur as S/sup 2/minus// and S/sup 6+/ on the surface. The presence of S/sup 6+/ along with the changes in E/sub b/ of the electrons in the T-Mo-W catalyst indicates the formation of MoS/sub 2/ and TiO(SO/sub 4/) species.
