Complete oxidation without formation of bulk CoO results when cobalt clusters stabilized with R 4 N + X − are exposed to O 2 . Since the resulting soluble, nanostructured cobalt( II ) oxide clusters (idealized representation below: dark spheres: metal atoms; light spheres: oxygen atoms; R C 8 H 1− ) do not penetrate very far into the pores of Al 2 O 3 pellets, unlike the Co clusters, these materials are potential shell catalysts.
