摘要： The present invention relates to an apparatus and method for producing metal nanoparticles using granule-type electrodes, in which a pair of electrode housings spaced apart from each other is filled with metal granules, and electrolysis is performed on the metal granules using alternating current, to thereby mass produce metal nanoparticles having a uniform shape in a continuous and inexpensive manner. The apparatus of the present invention comprises: a reaction container in which an electrolytic solution is contained; a first electrode and a second electrode which are formed by filling a first electrode housing and a second electrode housing, which are spaced apart from each other in the reaction container, with a plurality of metal granules or flakes; and a power supply device for applying alternating current power between the first electrode and the second electrode so as to induce an electrolysis reaction. The first electrode housing and the second electrode housing have a plurality of holes or slits formed at the opposite surfaces thereof, respectively, so as to discharge metal ions eluted by the electrolysis reaction.

摘要： Disclosed are a method and apparatus for producing metal nanoparticles using alternating current electrolysis, which maintain the concentration of a reducing agent and a dispersing agent at a constant level in proportion to the electric current intensity when synthesizing metal nanoparticles through alternating current electrolysis, to thereby significantly improve nanoparticle yield. The method for producing metal nanoparticles comprises: a step of dissolving an electrolyte and a dispersing agent in pure water in a reaction vessel to prepare an electrolyte; a step of installing a first electrode and a second electrode made of materials identical to those of the metal nanoparticles to be synthesized, such that the first electrode is spaced apart from the second electrode; a step of applying alternating current power to the space between the first electrode and the second electrode to ionize metals of the first electrode and the second electrode into the electrolyte; and a step of injecting a reducing agent for reducing metal ions into the electrolyte such that the concentration of the reducing agent can be maintained at a constant level in accordance with the concentration of metal ions produced per hour, to thereby reduce metal ions and synthesize metal nanoparticles.
