The influences of oxidation states of [RuO x ] + ( x =1—3) on the thermal activation of CH 4 and H 2 have been revealed: for CH 4 activation, higher oxidization states lead to the deeper oxidation products with increased reactivity; whereas an inverse reactivity trend was found in H 2 activation. Theoretical analysis indicates that the reduction of metal center drives the overall oxidation of CH 4 , and the back‐bonding orbital interactions between the cluster ions and H 2 control the H–H bond activation.
