Cerium oxide, zirconium oxide, Ce / Zr composite oxide and Ce / Zr solid solution with improved thermal stability and oxygen storage capacity

摘要

The production of cerium oxides, zirconium oxides, (Ce,Zr)O2 mixed oxides and (Ce,Zr)O2 solid solutions having improved particle size distribution, surface area, oxygen storage capacity and pore volume by the addition of an additive, such as anionic surfactants, nonionic surfactants, polyethylene glycols, carboxylic acids, and carboxylate salts, during the formation of the oxides or precursors thereof.
