Abstract
A method of making an oxygen storage material (OSM) with developed mesoporosity having a small fraction of pores <10 nm (fresh or aged), and resistance to thermal sintering is provided. This OSM is suitable for use as a catalyst and catalyst support. The method of making this oxygen storage material (OSM) includes the preparation of a solution containing pre-polymerized zirconium oligomers, cerium, rare earth and transition metal salts; the interaction of this solution with a complexing agent that has an affinity towards zirconium; the formation of a zirconium-based precursor; and the co-precipitation of all constituent metal hydroxide with abase.
