| titleOfInvention |
Compositions based on cerium oxide, zirconium oxide and, optionally, another rare earth oxide, having a specific raised surface at 1100 ·c, method for the production and use thereof as a catalyst |
| abstract |
The composition of the invention, according to a first embodiment, consists of essentially a cerium oxide and a zirconium oxide in a Ce / Zr atomic ratio of at least 1. According to a second embodiment, this composition is based on a cerium oxide, a zirconium oxide in an atomic ratio Ce / Zr of at least 1 and at least one oxide of an earth rare other than cerium. After calcination at 1100 ° C., it has a surface area of at least 9 m2 / g in the case of the first mode and at least 19 m2 / g in the case of the second. The composition of the invention can be used as a catalyst especially for the treatment of exhaust gases internal combustion engines. |
