Smirnov, A. Kalinkin, V. Bukhtiyarov] The reactions of the platinum and rhodium model catalysts applied to aluminum oxide with NOx (10 Torr NO + 10 Torr O2) were studied by X-ray photoelectron spectroscopy. The reaction conducted at room temperature formed on the surface of the oxide support the NO 3,s − nitrate ions characterized by the N1s line at 407.4 eV and O1s line at 533.1 eV and the NO 2,s − nitrite ions characterized by the N1s line with a binding energy of 404.7 eV. At the same time, the Pt4f and Rh3d lines of the supported platinum particles are shifted toward higher binding energies by 0.5-1.0 eV and 0.7-1.2 eV, respectively. It is assumed that the binding energies increase due to changes in the chemical state of the platinum metal in which oxygen is dissolved. The reaction of NOx with Pt/Al2O3 at 200°C forms platinum oxide defined by the Pt4f 7/2 line with a binding energy of 72.3 eV.
