Continuous synthesis method and continuous synthesis apparatus for core-shell structured nanoparticles of metal core / oxide shell and core-shell structured nanoparticles

摘要

This invention addresses the problem of providing a method and apparatus for continuously synthesizing nanoparticles in few processes and without causing variation in particle size or aggregation, as well as providing a core-shell structure nanoparticle. This invention concerns a continuous synthesis method for core-shell structure nanoparticles, a continuous synthesis apparatus, and core-shell structure nanoparticles synthesized by this continuous synthesis method and/or this continuous synthesis apparatus, wherein: the continuous synthesis method for core-shell structure nanoparticles continuously synthesizes metal nanoparticles having a diameter of 1-100 nM through an initial stage flow-type reaction tube (3) comprising at least a single stage flow-type reaction tube, hydrolyzes an oxide precursor in a subsequent stage flow-type reaction tube (10) comprising at least a single stage flow-type reaction tube, and uniformly heats at least the flow-type reaction tube (3) through microwaves; and the continuous synthesis apparatus has initial and subsequent stage flow-type reaction tubes (3, 10), and has a means for uniformly heating at least the flow-type reaction tube (3) through microwaves, the flow-type reaction tube (3) being a reaction tube for metal core synthesis, and the other flow-type reaction tube (10) being a reaction tube for oxide shell synthesis.
