摘要：

Oxygen adsorption on Pt(110)(1 × 2) has been studied by photoemission of adsorbed xenon (PAX). The presence of oxygen on the surface does not change the adsorption kinetics on the xenon at 42 K, but the binding energy between the xenon and the substrate is lowered by around 1.5 kcal/mol. The results show that oxygen is first adsorbed in the valleys of the surface, then on the facets. © 1990.
