Exhaust gas purification catalyst |
abstract |
Provided is an exhaust gas purification catalyst that includes a first catalyst layer (12), wherein: the first catalyst layer (12) includes a first section (14) and a second section (15) along the direction of flow of an exhaust gas; the first section (14) is located upstream from the second section (15) in the direction of flow of the exhaust gas; the first section (14) and the second section each include a catalyst active constituent that contains a specific element; the concentration of the specific element is greater in the first section (14) than in the second section (15); and the concentration gradient of the specific element in the first section (14) in the thickness direction of the catalyst layer (12) is gentler than the concentration gradient of the specific element in the second section (15) in the thickness direction. |
