<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a catalyst material which inhibits sintering of a catalyst component, and can raise heat resistance, and to provide a catalyst material and a catalyst body which are manufactured by the same. <P>SOLUTION: The method for manufacturing a catalyst material includes: a first process which prepares a dispersion of a particle which has an oxygen occlusion discharge function, and consists of a composite oxide of two or more elements chosen from the group consisting of Ce, Zr, Al, Ti, Si, Mg, Y, and La, and a dispersion of a particle which has heat resistance, and consists of a composite oxide of Al and La; and a second process in which the dispersion of a particle which has an oxygen occlusion discharge function and the dispersion of a particle which has heat resistance are mixed, and which distributes the particle which has an oxygen occlusion discharge function, and the particle which has heat resistance in a mixed liquid, wherein low molecule amines are used as at least one dispersant of the particle which has an oxygen occlusion discharge function and the particle which has heat resistance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
