Support - a method for producing a metal nanoparticle composite, a method of adjusting the surface area of ​​the preparation and metal nanoparticles fusion of the metal nanoparticles fusions

摘要

PROBLEM TO BE SOLVED: To provide a method capable of producing a metal nanoparticle fused body having more excellent continuity, self-supportability, mechanical strength and durability, etc.;SOLUTION: The method for producing a support-metal nanoparticle composite body comprises: a stage (A) where a metal ion-containing compound dissolved in a first solvent is impregnated into a support; a stage (B) where the support after the impregnation is dipped into a second solvent having a solubility lower than that of the first solvent; and a stage (C) where the metal ion-containing compound impregnated into the support after the immersion is reduced, so as to be metal nanoparticles.;COPYRIGHT: (C)2007,JPO&INPIT
