Abstract
It is aimed at creating noble metal nanoparticles having novel shapes, sizes, and arrangements usable for catalysts, electrodes, and the like. Micelles made into rod-like shapes having semicylindrical cross-sections are formed on a carrier substrate in a self-creating manner and immobilized thereon; noble metal ions are added and diffused in the micelles to complex the micelles with noble metal ions; and a reducing agent is subsequently caused to act thereon to progress a reductive reaction of noble metal within the immobilized micelles as reaction fields, thereby growing single crystalline noble metal ultrathin-film nanoparticles on the carrier substrate by utilizing the fixed micelles having the shapes as templates, respectively.
