    摘要: The present invention provides a metal cluster-carrying metal oxide support wherein a metal cluster obtained by use of a dendrimer is prevented from migrating to the surface of support and being sintered, and a process for production thereof. The process for producing the metal cluster-carrying metal oxide support of the present invention comprises (a) coordinating a first metal ion to a dendrimer 10, (b) reducing the first metal ion coordinated to the dendrimer to precipitate a cluster 6a of the first metal in the dendrimer, (c) further coordinating a second metal ion 8 to the dendrimer, and (d) drying and firing the solution containing this dendrimer on a metal oxide support 9, wherein the oxide of the second metal is the same as the metal oxide constituting the metal oxide support, or a metal oxide capable of forming a composite oxide with the metal oxide constituting the metal oxide support. In the metal cluster-carrying metal oxide support of the present invention, the cluster 6a of the first metal is held by the oxide of the second metal 8 on the metal oxide support 9.
