摘要：PROBLEM TO BE SOLVED: To provide a catalyst material that becomes active even at low temperatures and has catalyst performance excellent enough to purify hazardous substances in exhaust gas efficiently.SOLUTION: An exhaust gas purification catalyst 1 includes a Rh-containing catalyst layer 4 provided on a base material 2. The Rh-containing catalyst layer 4 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.
