<P>PROBLEM TO BE SOLVED: To provide a catalyst consisting of a support containing ceria and an active species supported on the support, which can control the particulate growth of the active species. <P>SOLUTION: The method for producing the catalyst includes: a process for mixing a cerium salt and a strong alkaline aqueous solution to prepare a mixed solution; a process for hydrothermally synthesizing the mixed solution to form the support that contains CeO2 nanorods consisting of a ä100} surface and a ä110} surface; a process for dispersing the support that contains the CeO2 nanorods in water to prepare a support dispersion liquid; a process for dispersing metal fine particles in water to prepare a metal fine particle-dispersed liquid; and a process for mixing and agitating with heating the support dispersion liquid and the metal particle dispersion liquid to support the metal particles on the support that contains the CeO2 nanorods. <P>COPYRIGHT: (C)2013,JPO&INPIT |
