Abstract

The present disclosure provides an exhaust gas purification catalyst having improved performance for purifying an exhaust gas, in particular, an exhaust gas containing NOx. The exhaust gas purification catalyst of the present disclosure includes Rh-supporting composite oxide support particles containing Al, Zr, and Ti and Rh-supporting aluminum phosphate-based support particles. Furthermore, in the exhaust gas purification catalyst of the present disclosure, the ratio of the moles of metals constituting the aluminum phosphate-based support particles, relative to the total moles of metals constituting the composite oxide support particles and the aluminum phosphate-based support particles is 7.5% or more and 15.0% or less.
