Abstract: XP Spectroscopy is used to compare the states of the supported platinum particles in the samples of the Pt/Sibunit catalyst and the Pt/HOPG model system after treating in NO2 at room temperature and pressure of 3 × 10−6 mbar. It is shown that in both cases the platinum particles are not oxidized completely. The comparison of the spectra obtained for the Pt/Sibunit sample in the Pt 4f and Pt 3d5/2 regions with the use of Al Kα and Ag Lα radiations serves as a basis for an assumption that the particles of platinum after being treated in NO2 have the core (metallic Pt) − shell (platinum oxides) structure.
