Compound oxide having oxygen absorbing and desorbing capability and method for preparing same. |
| 摘要 |
<p>A compound oxide having oxygen absorbing and desorbing capability contains 4.99-98.99% by weight of cerium oxide, 1-95% by weight of zirconium oxide and 0.01-20% by weight of hafnium oxide. The compound oxide has an oxygen absorbing and desorbing capability of at least 100 mu mol/g at 400-700 DEG C and a specific surface area of at least 10 m<2>/g after heating at 900 DEG C for 5 hours.</p> |
