  • Patent number: 11969712
    Abstract: A catalyst for purification of exhaust gas in which Pd-based nanoparticles and ceria nanoparticles are supported on a composite metal oxide support containing alumina, ceria, and zirconia, wherein a molar ratio (Ce/Pd) of Ce and Pd supported on the support is 1 to 8, a proximity ? between Pd and Ce is 0.15 to 0.50, wherein the proximity ? is determined, based on Pd and Ce distribution maps in an element mapping image of energy dispersive X-ray analysis, by the following formula (1): ? = ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( ( I ? ( i , j ) - I ave ) ? ( T ? ( i , j ) - T ave ) ) ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( I ? ( i , j ) - I ave ) 2 - ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( T ? ( i , j ) - T ave ) 2 , ( 1 ) a Pd dispersity after a heat-resistance test at 1050° C. for 25 hours is 0.8% or more.
