For Pd/MgO(100) pre-exposed to oxygen, the catalytic oxidation of CO and D2, respectively, has been studied in the temperature range 100–300 _C. At temperatures >200 _C, the CO2 desorption rate is independent of oxygen coverage, _O, and the reactive sticking coefficient for CO is close to unity. The D2O desorption rate is strongly dependent on _O. D2 adsorption is blocked by adsorbed oxygen and the maximum D2O desorption rate is reached when almost all oxygen has been consumed (_O < 0:03). The formation of an oxygen c(2 _ 2) structure, coexisting with the initial p(2 _ 2) phase, is reflected in the oxidation rates.
