Abstract

Monodispersed supported clusters of catalytically important materials provide an excellent platform for model catalytic studies. Ultimately such systems can provide the detailed understanding of the site specific reactivity and yield the structure-reactivity relationships that cannot be obtained otherwise. Unfortunately preparation of such model systems requires highly complex experimental apparatus and has been achieved only for limited number of clusters, primarily those of metals.[1] Our work in this area focuses on supported transition-metal oxide catalysts which are of particular technological importance and have broad applications in partial oxidation of alcohols, oxidative dehydrogenation of hydrocarbons, and selective reduction of nitric oxide
