摘要
Three case studies to demonstrate the ability to characterize oxidation model catalysts and reactions of these systems at the atomic level are reviewed. Firstly, results on small Au aggregates on a clean MgO(100) surface which are interesting model systems for low temperature oxidation are considered. Secondly, oxidative dehydrogenation of methanol on alumina-supported Pd is addressed. The problem of oxygen storage in and on the Pd particles is studied for nanoparticles on Fe3O4(111). Finally, morphology-spectroscopy relations for oxide-supported so-called monolayer vanadia catalysts are investigated. (C) 2006 Elsevier B.V. All rights reserved.
