Microwave irradiation device and method of producing metal nanoparticles

Abstract

Provided is a microwave irradiation device for producing metal nanoparticles and a method of producing metal nanoparticles that allow preparing metal nanoparticles with small and uniform particle sizes. The present disclosure relates to a microwave irradiation device and a method of producing metal nanoparticles using the device. The microwave irradiation device includes a reaction vessel for housing a reaction solution including a raw material of metal nanoparticles, a cooling mechanism that cools the reaction vessel from outside, and a microwave irradiation source for irradiating the reaction solution with a microwave. A solid substance having a dielectric constant lower than a dielectric constant of the reaction solution is disposed in the reaction vessel.

Dependencies are inferred from the claim text.
