<P>PROBLEM TO BE SOLVED: To provide a method for easily depositing a nano-ordered gold fine particle or gold cluster on a carrier in a short time regardless of the material of the carrier. <P>SOLUTION: A sublimable gold precursor (a dimethyl-gold-acetylacetonate complex, a dimethyl-gold-trifluoroacetylacetonate complex, a chlorotrimethylphosphine-gold complex, a methyl(trimethylphosphine)-gold complex or the like) and the inorganic or organic carrier (a polymer, an inorganic oxide, activated carbon, a porous metal complex or the like) are mixed in a solid phase at room temperature under normal pressure while imparting mechanical friction to them and then the obtained mixture is deoxidized so that the gold fine particle is dispersed and fixed to the surface of the carrier. The obtained gold nanoparticle- or gold cluster-deposited carrier exhibits excellent characteristics when used as an oxidation catalyst for oxidizing glucose into a gluconic acid, or a colorant. <P>COPYRIGHT: (C)2009,JPO&INPIT |
