Abstract

An exhaust gas purification catalyst includes a Rh-containing catalyst layer provided on a base material. The Rh-containing catalyst layer includes Rh-supporting Zr-based composite oxide in which Rh6 is supported on Zr-based composite oxide containing Zr and a rare earth metal except Ce. The Rh-supporting Zr-based composite oxide has been previously subjected to a reduction treatment.
