Summary:

We have reported the innovation of "An Intelligent Catalyst" which has the function for self-regeneration of Pd realized through the solid solution and segregation of Pd in a perovskite crystal.In this study, we did further research on regeneration for three different precious metals (Rh, Pd and Pt) in two types of perovskite systems (LaCeFeO3 and LaCeCoO3). In perovskite catalysts loaded with precious metals, the durability of the perovskite structure in redox fluctuation at high temperature is indispensable to suppression of the grain growth of precious metals.The key technology for the development of intelligent catalysts is considered to be the affinity of precious metals to durable perovskite oxides. In the six kinds of perovskite catalysts investigated here, only the Pd loaded LaCeFeO3 catalyst was considered "intelligent"
