摘要：
Compositions based on zirconium oxide, including 1 to 20% yttrium oxide, 1 to 30% tungsten oxide and the balance zirconium oxide, have a specific surface area of at least 40 m2/g after calcination at 700° C. for 4 hours and an acidity measured by the methylbutynol test of at least 90%, and are useful as catalyst or catalyst supports, especially for the treatment of motor vehicle exhaust gases.
