PRECIPITATED AND CALCINED COMPOSITION BASED ON ZIRCONIUM OXIDE AND CERIUM OXIDE

摘要

The present invention relates to compositions based on zirconium oxide and cerium oxide that exhibit a sufficiently high specific surface area after calcination and a low maximum reduction temperature of the oxide after calcination. Compositions of the present invention may be notably used in various catalytic systems, such as for the treatment of exhaust gases from internal combustion engines.
