Apparatus and method for manufacturing metal nanoparticle dispersion, method for manufacturing metal nanoparticle support, metal nanoparticle, metal nanoparticle dispersion, and metal nanoparticle support

摘要

To provide an apparatus and method for manufacturing a metal nanoparticle dispersion with which a metal nanoparticle dispersion can be manufactured without using expensive reagents or equipment, and to provide a method for manufacturing a metal nanoparticle support, metal nanoparticles, a metal nanoparticle dispersion, and a metal nanoparticle support. This apparatus for manufacturing a metal nanoparticle dispersion is characterized in comprising: a jetting part for jetting a metal-salt solution or dispersion in which a metal salt has been dissolved or dispersed in a first liquid; a voltage-impressing part for applying a voltage to the jetting part 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 droplets of the metal-salt solution or dispersion to be jetted from the jetting part, and causing the second liquid to attract the droplets.
