Aluminum-based and zirconium-based mixed oxides
The invention relates to a mixed oxide of aluminum, zirconium, cerium, lanthanum and optionally at least one rare earth metal other than cerium and lanthanum, which makes it possible to produce a catalyst that maintains good thermal stability and good catalytic activity after severe aging. The invention also relates to a method for preparing such a mixed oxide and to a method for treating exhaust gases from internal combustion engines using a catalyst prepared from such a mixed oxide.
本发明涉及铝、锆、铈、镧和任选地至少一种除铈和镧之外的稀土金属的混合氧化物，其使得可以制备在严重老化后保持良好热稳定性和良好催化活性的催化剂。本发明还涉及用于制备此混合氧化物的方法，并且还涉及一种用于使用由此混合氧化物制备的催化剂处理来自内燃机的排气的方法。
