Exhaust gas purification catalyst and method for producing the same |
摘要 |
An exhaust gas purification catalyst includes a Rh-containing catalyst layer provided on a base material. The Rh-containing catalyst layer includes a binder material of Rh-doped CeZr-based composite oxide containing Ce and Zr and doped with Rh. The binder material has been previously subjected to a reduction treatment. |
