METHOD AND APPARATUS FOR PRODUCING NANO-SIZED SILVER PARTICLES USING ELECTROLYSIS

摘要

The present invention relates to a method and an apparatus for producing nano-sized silver particles, which produce nano-sized silver particles of uniform shape and size in an environmentally friendly and simple manner using electrolysis. The method of the present invention comprises: a step of dissolving a reductant and an electrolyte into water in a reaction vessel to prepare an electrolytic solution; a step of arranging a cathode rod made of a material different from nano-sized silver particles to be obtained, in the electrolytic solution such that the cathode rod is rotatable in the reaction vessel, and arranging at least one anode made of silver (Ag) such that the anode is spaced apart from the cathode rod; a step of stirring the electrolytic solution, rotating the cathode rod to prevent a precipitation of silver crystals on the surface of the cathode rod, and performing electrolysis to apply direct current power between the cathode rod and the anode to ionize the silver of the anode into the electrolytic solution; and a step of reducing the silver ion by a reductant to obtain nano-sized silver particles.
