METHOD AND APPARATUS FOR PRODUCING METAL NANOPARTICLES USING ALTERNATING CURRENT ELECTROLYSIS

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.
