Abstract:
The interaction of NO2 with a carbon material from the Sibunit family with palladium metal particles supported on its surface was studied by X-ray photoelectron spectroscopy (XPS) at a pressure of 10–6 mbar in a temperature range from room temperature to 300°C. Two Pd/Sibunit samples, one of which was prepared by chemical deposition of palladium (Pd/C-HC sample) and the other, by vacuum evaporation of the metal onto the support (Pd/C-VE sample), were studied. Both of the samples showed similar behaviors in the interaction with NO2. Over the entire temperature range, the C1s spectrum of the samples contained a single peak with a binding energy of 284.4 eV from carbon atoms in the sp2-hybrid state, which indicated a weak effect of NO2 on Sibunit. At temperatures from room temperature to 150°C, the state of palladium supported onto the surface of Sibunit also did not change, but palladium was partially oxidized with the formation of PdO in a range from 200 to 300°C.
