Piednoir, M. Languille, L. Piccolo, A. Valcarcel, F. Cadete Santos. Aires, J. Bertolini] The oxidation of CO on Pd(111) and Pd70Au30(111) has been studied under pressures upto 100Torr. 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 occurs. This is ascribed to a switch from CO-induced inhibition of O2 adsorption to a regime determined by CO adsorption. The other kinetic features are explained by oxidation of palladium and adsorption-induced restructuring of the surfaces.
