Chapter

Abstract

Gas phase cluster studies can be employed to investigate the reactions occurring on a catalyst surface, thereby providing a complementary method to model the reaction mechanisms of condensed phase catalysis. Utilizing a guided ion beam mass spectrometer, studies are directed toward unraveling the influence of factors such as size, stoichiometry, oxidation and ionic charge state, elemental composition, and structure on the reactivity of metal oxide clusters. Particular emphasis is on identifying individual species that play an important role in effecting oxidation reactions and aid in elucidating the molecular level mechanisms of oxygen transfer processes.
