Abstract
Exhaust gas purification device having a catalyst layer including an Rh—Ba-loaded catalyst, and a Pt/Pd—Ba-loaded catalyst. The exhaust gas purification device satisfies at least one of (a) the degree of Rh—Ba dispersion is greater than 0.001 and less than 1.000, (b) the loaded amount of Ba based on the weight of a first carrier particle in the Rh—Ba-loaded catalyst is greater than 0.01% by weight and less than 10.00% by weight, and the loaded amount of Ba based on the weight of a second carrier particle in the Pt/Pd—Ba-loaded catalyst is 10.00% by weight to 20.00% by weight, and (c) the loaded amount of Ba based on the weight of the first carrier particle in Rh—Ba-loaded catalyst is greater than 0.005 times to less than 0.800 times the loaded amount of Ba based on the weight of the second carrier particle in Pt/Pd—Ba-loaded catalyst.
