Abstract: Particles for an exhaust gas purification catalyst including: inorganic oxide particles; and an inorganic coating layer covering the inorganic oxide particles. The particles for an exhaust gas purification catalyst have reduced cumulative pore volume in a pore diameter range of 0.1-20 μm compared to a cumulative pore volume in a pore diameter range of 0.1-20 μm of inorganic oxide particles before being coated with the inorganic coating layer. Accordingly, the particles for an exhaust gas purification catalyst have a higher thermal conductivity than the inorganic oxide particles before being coated with the inorganic coating layer.

Abstract: The exhaust gas purifying catalyst presented here includes a substrate and a catalyst coat layer formed on the surface of the substrate. The catalyst coat layer is formed in a laminate structure having two layers, with a first layer being nearer to the surface of the substrate and a second layer being relatively further from this surface. The second layer includes a carrier and a noble metal supported on the carrier. The first layer is a noble metal-free layer that does not contain a noble metal but does contain an OSC material having oxygen storage capacity.
