The effects of oxygen and water vapor on the nature and yield of sulfur-containing products were studied. The parameters bound up with each peak in the software were binding energy centre, full width at half maximum (FWHM), peak area, and the Gaussian-to-Lorentzian ratio. The formation of aluminum and cerium sulfates and sulfites on model Pt/Al2O3 and Pt/CeO2 catalysts occurred simultaneously with the formation of surface platinum sulfides (Eģ/2 is 162.2 eV). High-resolution XPS C1s (a), O1s (b), S2p, and N1s spectra of the Cu5Zn5Al1Sn alloy surface before and after addition of inhibitors in 3.5 wt. The software of XPS Peak 4.1 was adopted to de-convolve the Cu2p, C1s, O1s, N1s, S2p, and Si2p peaks using the Shirley-type background 4. The formation of sulfates on the surface of CeO2 occurred much more effectively than in the case of Al2O3, and it was accompanied by the reduction of Ce(IV) to Ce(III). The sulfur chemical environment can be more clearly studied by means of the S2p core level spectrum, shown inFig.1(d),wheretwodoublets,peakedat162.4eVand163. The formation of surface sulfite at T ≥ 473 K (the S 2pī) is 167.5 eV) and surface sulfate at T ≥ 573 K (Eī = 169.2 eV) was observed in the reactions of Al2O3 and CeO2 with SO2. The most intense singlet peak is due to the S2s emission from defect-free regions of MoS 2,while the additional singlet peak at 227.6 eV corresponds to sulfur close to a defect. The interactions of Al2O3, CeO2, Pt/Al2O3, and Pt/CeO2 films with SO2, SO2 + H2O, SO2 + O2, and SO2 + O2 + H2O in the temperature range 300–673 K at the partial pressures of SO2, O2, and H2O equal to 1.5 × 102, 1.5 × 102, and 3 × 102 Pa, respectively, were studied using X-ray photoelectron spectroscopy.
