Abstract
A method and apparatus for producing core-shell type metal nanoparticles which are excellent in productivity are provided, in particular, the present invention provides a method of production of core-shell type metal nanoparticles including (a) a step of introducing a solution of a salt of a first metal to a first flow path of a flow type reaction apparatus and applying plasma to the solution of the salt of the first metal in the first flow path to obtain a solution which contains metal nanoparticles of the first metal and (b) a step of introducing a solution of a salt of a second metal to a second flow path of the flow type reaction apparatus, making it merge with the solution which contains metal nanoparticles of the first metal to obtain a mixed solution, and applying plasma to the mixed solution to cover the metal nanoparticles of the first metal by the second metal.
