Abstract:
The interaction of O2 with Pd(110) has been studied by TDS and XPS at T = 400 K and at pressures PO2 from 2.6x10-6 to 10 Pa. At low exposures in O2 (e<1-5 L), an adsorption layer with teta of ca.0.5 and with the O1s peak at BE = 529.3 eV has been found to form on the surface. When e grows from 5 to 108 L, the position and intensity of the oxygen O1s peak remain practically constant. At the same time, as much as 5 mL of oxygen is absorbed according to the TDS data. The results obtained by TDS and XPS indicate that oxygen penetrates deep into the subsurface layers of palladium (>15-20 Å) and is distributed in its bulk in a low concentration.
