摘要
Compounds having the perovskite-type AB03 structure wherein 1 to 20% of the B site cations are Ru or Pt, the remainder consisting essentially of cobalt, preferably partially tetravalent and the A sites being occupied by a mixture of lanthanide ions and ions of Group IA, IIA, and IVA of the Periodic Table having an ionic radius of about 0.9 to about 1.65 A are useful catalysts for reduction and oxidation reactions, particularly for the cleanup of exhaust gases of internal combustion engines.
