A matter of radical sites and bond energies : Experimental and theoretical studies show that the cationic polynuclear aluminum oxide clusters, which are oligomeric systems of (Al 2 O 3 ) x + ( x =3, 4, 5), activate methane at room temperature (see picture). In contrast, clusters with an odd number of aluminum atoms are unreactive.
