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 H2S-SO2 and H2S-O2 gas mixtures, which serve as models for the technological gases in Klaus apparatuses and the direct catalytic oxidation of H2S. X-ray photoelectron spectroscopy was used to establish the formation of sulfur as S2- and S6+ on the surface. The presence of S6+ along with the changes in Eb of the electrons in the T-Mo-W catalyst indicates the formation of MoS2 and TiO(SO4) species.
