Abstract

The subject matter of the invention is a method for producing composites, comprising mixed oxides of aluminum oxide and cerium/zirconium, hereinafter referred to briefly as Al/Ce/Zr oxide composite(s), using boehmite and soluble cerium/zirconium salts. Al/Ce/Zr oxide composites produced in this way have an increased thermal stability.
