The chemisorption of O2and CO on Pt metal: An SCF-Xα study

Abstract
The results of SCF-Xα cluster calculations are presented in an attempt to model the chemisorption of O2 and CO on platinum surfaces. In the case of O2 we show that the adsorbed molecular oxygen is partially dissociated whereas adsorbed CO is energetically more stable when adsorbed on a surface site than when adsorbed on a hole site. The latter finding is in agreement with a recent SIMS study.
