I will discuss catalysis by oxides that are substitutionally doped with cations whose valence is higher than that of the cations they replace in the host oxide. I will show examples of catalytic behavior for three situations. 1. The host oxide is irreducible and the valence of the dopant is not much higher than that of the cation in the host. 2. The host oxide is irreducible and the dopant has much higher valence. 3. The host oxide is reducible.  In these situations, doping will activate the breaking of the C-H bond in an alkane but it will do this by different mechanisms.  I will also discuss the stability of these systems and the difference between the cases when the host oxide is reducible or irreducible.
