PEROVSKITE-TYPE COMPOSITE OXIDE, CATALYST COMPOSITION AND METHOD FOR PRODUCING PEROVSKITE-TYPE COMPOSITE OXIDE |
摘要 |
To provide a perovskite-type composite oxide which has stable quality in which a solid solution of Pd is formed at a high rate, a method for producing the perovskite-type composite oxide, and a catalyst composition containing the perovskite-type composite oxide, the perovskite-type composite oxide is produced by formulating materials in accordance with each atomic ratio of a perovskite-type composite oxide represented by the following general formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒA x B (1-y) Pd y O 3+´ €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein A represents at least one element selected from rare earth elements and alkaline earth metals; B represents at least one element selected from transition elements (excluding rare earth elements, and Pd), Al and Si; x represents an atomic ratio satisfying the following condition: 1 < x; y represents an atomic ratio satisfying the following condition: 0 < y ‰¤ 0.5; and ´ represents an oxygen excess.
