  • Publication number: 20120318678
    Abstract: An apparatus for producing metal nanoparticles using granule type electrodes, in which the metal nanoparticles having a uniform shape and nano-size are continuously mass-produced at low cost by filling metal granules in a pair of electrode housings spaced by a certain interval and electrolyzing the granules with alternating-current voltage. The apparatus includes a reaction vessel containing an electrolytic solution, first and second electrodes that are formed by filling a number of granules or flakes, in first and second electrode housings that are spaced by a gap in the reaction vessel, and a power supply that applies an alternating-current power between the first and second electrodes for electrolysis reaction, in which the first and second electrode housings comprise a number of holes or slits on at least two surfaces facing each other so that metal ions dissolved from the first and second electrodes can be discharged depending on the electrolysis reaction.

  • Publication number: 20110068013
    Abstract: Disclosed herein are a method and apparatus for preparing metal nanoparticles using alternating current (AC) electrolysis, in which the yield of metal nanoparticles obtained can be greatly improved by maintaining the concentrations of a reducing agent and a dispersing agent at constant levels in proportion to the intensity of an electric current during the production of the metal nanoparticles.
