摘要：
A one-layer three-way catalyst is described for the cleaning of the exhaust gases of internal combustion engines with outstanding activity and thermal stability. The catalyst comprises an active aluminum oxide, a first cerium/zirconium mixed oxide and a second cerium/zirconium mixed oxide. The first cerium/zirconium mixed oxide has a higher zirconium oxide content than the second mixed oxide. The first cerium/zirconium mixed oxide is catalytically activated with rhodium and the second cerium/zirconium mixed oxide with palladium.
