SINGLE CRYSTALLINE NOBLE METAL ULTRATHIN FILM NANOPARTICLES FORMED USING, AS REACTION FIELD, ADSORBED MICELL FILM FORMED AT SOLID/LIQUID INTERFACE AND PROCESS FOR PRODUCING THE SAME

摘要

This invention provides noble metal nanoparticles that have novel form, size and arrangement and can be used, for example, in catalysts and electrodes. Micells, which are semicylindrical in section and are formed in a rod form, are self-created and fixed on a carrier substrate. A noble metal ion is added and dispersed in the micells to combine the micells with the noble metal ion. Next, a reducing agent is allowed to act, whereby the inside of the fixed micelle is used as a reaction field to allow a reduction reaction of the noble metal to proceed, and single crystalline noble metal ultrafine thin film nanoparticles are grown on a carrier substrate using the fixed micells having the above shape as a template.
