Apparatus and method for producing a metal nanoparticle dispersion, method for producing a metal nanoparticle support, metal nanoparticles, metal nanoparticle dispersion and metal nanoparticle support

摘要

Providing an apparatus and method for producing a metal-nanoparticle dispersion capable of producing a metal nanoparticle dispersion without using expensive reagents or equipment, and for providing a method of making a metal-nanoparticle support, metal Nanoparticles, a metal nanoparticle dispersion, and a metal nanoparticle carrier. This metal nanoparticle dispersion producing apparatus is characterized by comprising: an ejection portion for ejecting a metal salt solution or dispersion in which a metal salt has been dissolved or dispersed in a first liquid; a voltage applying part for applying a voltage to the ejection portion and electrifying the metal salt solution or dispersion; and a potential difference forming means for forming a potential difference between a second liquid in which the metal salt solution or dispersion has been dispersed and the electrified metal salt solution or dispersion, causing the droplets of the metal salt solution or dispersion to be ejected from the ejection part, and causing that the second liquid attracts the droplets.
