Pd(111) versus Pd-Au(111) in carbon monoxide oxidation under elevated pressures

The oxidation of CO on Pd(111) and Pd70Au30(111) has been studied under pressures upto 100 Torr. Gold is found to decrease the surface activity by inhibiting oxygen dissociation. For a sufficient conversion time depending on the CO coverage and the surface identity, a dramatic boost of activity occu...
