Title:
METHOD FOR PRODUCING COMPOSITE NOBLE METAL NANOPARTICLES, COMPOSITE NOBLE METAL NANOPARTICLES PRODUCED USING SAME, AND CATALYST CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2015/049959
Kind Code:
A1
Abstract:
The present invention provides a method for efficiently producing composite noble metal nanoparticles by means of a process that is low-energy, has a low environmental impact, and is simple. The method for producing composite noble metal nanoparticles includes a bioreduction step in which composite noble metal nanoparticles containing a plurality of types of noble metals in a single particle are precipitated by means of adding an electron donor and metal ion reducing bacteria to a starting material solution containing a plurality of types of noble metal ions, and reducing the noble metal ions by means of the metal ion reducing bacteria.
