Exhaust gas purification catalyst |
| abstract |
An object of the present invention is to provide a gas purification catalyst having improved NOx storage performance. An exhaust gas purification catalyst of the present invention includes ceria particles as a carrier and barium supported on the ceria particles. The ceria particles contain lanthanum on the surface thereof, and the ceria particles are converted into X-rays. When measured by photoelectron spectroscopy, the value of the molar ratio of lanthanum atoms to cerium atoms is 0.029 or more. [Selection] Figure 2 |
