摘要：

We have performed first principles pseudopotential calculations for catalytic CO oxidation on Pd doped Ag(111) surface. We discuss the effect of the change in the atomic geometry and surface electronic structure on the adsorption and reaction mechanism when alloying Ag with Pd. Pd doped Ag(111) works as a better catalyst for CO oxidation than the pure elemental Ag surface since Pd acts as an electronic promoter for the oxidation process. (C) 2003 Elsevier Ltd.
