ABSTRACT:
The present invention relates to a method for manufacturing copper-based nanoparticles, in particular, to a method for manufacturing copper-based nanoparticles, wherein the method includes producing CuO nanoparticles by mixing CuO micropowder and alkylamine in a nonpolar solvent and heating the mixture at 60-300° C.; and producing copper-based nanoparticles by mixing a capping molecule and a reducing agent with the CuO nanoparticles and heating the mixture at 60-120° C.According to the present invention, copper-based nanoparticles can be synthesized using CuO, but not requiring any inorganic reducing agent, in a high yield and a high concentration, so that it allows mass production and easy controlling to desired oxidation number of nanoparticles.
