英文摘要Adsorbed oxygen migration from noble metals to silver was investigated on both an Ag/Pt(110) model catalyst and Al2O3-supported Ag-Pd catalysts by photoelectron emission microscopy (PEEM) and oxygen temperature-programmed desorption (TPD). On the CO-precovered Ag/Pt(110) surface, oxygen was observed to diffuse from the Pt(110) surface to the Ag surface by PEEM. The diffusion of oxygen was coupled locally with a surface reaction of COad + O-ad, giving rise to rapid propagation of the oxygen front. Migration of oxygen from the Pd surface to the Ag surface was proved also by oxygen TPD experiments on Al2O3-supported Ag-Pd catalysts. Copyright (C) 2001 John Wiley & Sons, Ltd.
