EXHAUST GAS PURIFICATION CATALYST |
摘要 |
Provided is a technique by which excellent exhaust gas purification performances can be achieved. The exhaust gas purification catalyst (1) according to the present invention includes a substrate (10), and a first catalyst layer (20) formed on the substrate (10), the first catalyst layer (20) containing palladium and/or platinum and alumina doped with an alkaline-earth metal element. The exhaust gas purification catalyst (1) has a correlation coefficient Á Al,AE given by the following formula of 0.75 or more: Á Al , AE = C Al , AE à Al �¢ à AE |
