| 摘要 |
A catalyst for exhaust gas purification of the present invention contains the thin-plate-like ceria (CeO 2 ) as a catalytic active component. According to the catalyst for exhaust gas purification of the present invention, among CO, HC, and NOx, which are hazardous components contained in exhaust gas, particularly, NOx, can be removed efficiently. The present invention can be used as, what is called a NOx trapping catalyst, which stores NOx in oxidizing atmosphere, and discharges and reduces NOx in reducing atmosphere.
