Abstract

Complete oxidation without formation of bulk CoO results when cobalt clusters stabilized with R4N+X are exposed to O2. Since the resulting soluble, nanostructured cobalt(u) oxide clusters (idealized representation below; dark spheres; metal atoms; light spheres; oxygen atoms; R = C8H1-) do not penetrate very far into the pores of Al2O3 pellets, unlike the Co clusters, these materials are potential shell catalysts.
