The present disclosure relates to a method and an apparatus for manufacturing a core-shell catalyst, and more particularly, to a method and an apparatus for manufacturing a core-shell catalyst, in which a particle in the form of a core-shell in which the metal nanoparticle is coated with platinum is manufactured by substituting copper and platinum through a method of manufacturing a metal nanoparticle by emitting a laser beam to a metal ingot, and providing a particular electric potential value, and as a result, it is possible to continuously produce nanoscale uniform core-shell catalysts in large quantities.

Method and apparatus for manufacturing core-shell catalyst

To provide a reactor to improve evenness in the thickness of shell metals coated on the surface of core particles by increasing area sizes in the reactor chamber to control electric potentials, the present invention is configured to comprise a top surface able to move up and down while serving as a working electrode, a wall serving as a working electrode, a bottom surface, a standard electrode, a power supplying part and a solution injecting part, wherein the top surface can move up and down automatically by an electric motor or manually. Also, the top surface is configured to be suitable for the interior diameter of the reactor chamber, for solutions inside the reactor chamber not to leak from the top surface or from the crevice between the top surface and the wall of the reactor chamber. The bottom surface of the reactor chamber may comprise an impeller or an ultrasonic wave diffuser to bring about even diffusion in the reactor chamber.
