Oxygen storage material |
| abstract |
The invention provides an oxygen storage material having high oxygen storage capacity and high thermal durability. The oxygen storage material of the invention has some of the La sites of La<sub>2</sub>CuO<sub>4</sub> with a K<sub>2</sub>NiF<sub>4</sub>-type crystal structure replaced by Ce. The oxygen storage material may have the composition La<sub>(2.00-x)</sub>Ce<sub>x</sub>CuO<sub>4</sub> (0.20 ≥ x > 0.00). The oxygen storage material may also have a precious metal supported. The precious metal may be Pt, Pd or Rh. The exhaust gas purification catalyst is an exhaust gas purification catalyst comprising an oxygen storage material according to the invention. |
