ABSTRACT:
A process for producing a metallic-nanoparticle inorganic composite10includes an oxide film formation step in which an oxide film14having micropores is formed on a substrate by a sol-gel method in which a metal alkoxide is partly hydrolyzed by the action of an acid catalyst, a tin deposition step in which the oxide film14is brought into contact with an acidic aqueous solution of tin chloride, an excess Sn2+ion removal step in which Sn2+ions are removed from the micropores, a metallic-nanoparticle deposition step in which the oxide film14is brought into contact with an aqueous solution of a metal chelate to deposit metallic nanoparticles12in the micropores, and an excess metal ion removal step in which metal ions are removed from the micropores; and a metallic-nanoparticle inorganic composite10is produced by this process.
