Abstract
A process for producing a metallic-nanoparticle inorganic compositeincludes an oxide film formation step in which an oxide filmhaving 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 filmis brought into contact with an acidic aqueous solution of tin chloride, an excess Snion removal step in which Snions are removed from the micropores, a metallic-nanoparticle deposition step in which the oxide filmis brought into contact with an aqueous solution of a metal chelate to deposit metallic nanoparticlesin the micropores, and an excess metal ion removal step in which metal ions are removed from the micropores; and a metallic-nanoparticle inorganic compositeis produced by this process.
