<P>PROBLEM TO BE SOLVED: To provide a production method of an Au catalyst which enables a carrier to carry Au with a smaller particle diameter by dispersion with a simple step while keeping a degree of freedom of selection of the carrier to be used. <P>SOLUTION: An Au-compound solution and the carrier consisting of a metal oxide are prepared (Step S110). And, the Au-compound solution prepared is reduction treated to form a sol of Au-containing fine particles (Step S100). Thereafter, the sol of Au-containing fine particles and the carrier are mixed and the Au-containing fine particles are carried by the carrier (Step S120). An Au catalyst, wherein Au particles are dispersed to be carried by the carrier, is prepared from the carrier carrying the Au-containing fine particles (Step S130, S140). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
