Perovskite-supported metals have sometimes been referred to as "intelligent catalysts" because of the potential to regenerate sintered particles by driving the metal into the oxide lattice by high-temperature oxidation and releasing the metal by reduction. However, low surface areas and incomplete release of metal from the lattice have prevented the widespread application of these materials. Here, we describe the preparation of thin perovskite films on stable supports by atomic layer deposition (ALE)) as a means for avoiding the limitations associated with bulk perovskites. Examples will be given which demonstrate that many of the favorable properties of perovskite supports can be retained, while avoiding some of the shortcomings. Potential opportunities for using these materials are discussed.
