Title:

METAL NANOPARTICLE WITH SUPPORT, CONTINUOUS METAL NANOPARTICLE BODY, AND METHODS FOR PRODUCING THESE

Document Type and Number:

WIPO Patent Application WO/2004/106224

Kind Code:

A1

Abstract:

A method for producing a metal nanoparticle with a support is disclosed which comprises a step for having a support composed of an organic material adsorb a metal ion-containing compound, and a step for forming metal nanoparticles on the support by reducing the adsorbed metal ions. With this method, metal nanoparticles can be simply and accurately produced from a metal ion-containing compound in situ using various organic materials as a matrix.
