Abstract
The inventive composition, according to a first embodiment, consists essentially of a cerium oxide and a zirconium oxide in an atomic ratio Ce/Zr of at least 1. According to a second embodiment, said composition is based on cerium oxide, zirconium oxide with an atomic ratio Ce/Zr of at least 1 and at least one rare earth oxide other than cerium. After calcination at 1100° C., said composition has a specific surface of at least 9 m2/g in the second embodiment. The inventive composition can be used as a catalyst especially for the treatment of waste gases from internal combustion engines.
