Abstract
The oxidation of a polycrystalline platinum foil by nitrogen dioxide at an NO2 pressures of 10–6–10–4 mbar and a temperature of 525 K has been investigated by X-ray photoelectron spectroscopy (XPS). Under these conditions, the platinum oxides PtO and Pt3O4 form on the foil surface. A comparison between the data obtained in this study and the data on the oxidation of platinum nanoparticles suggests a hypothesis as to the causes of the size effect in the oxidation of NO over platinum catalysts.
