Abstract
It provides a method for preparing metal nanoparticles using a metal seed and metal nanoparticles including the metal seed, the method including: preparing a solution by adding a polymer surfactant in an alcohol solvent; heating the solution; forming a metal seed by adding a first metal salt of at least one metal salt selected from the group consisting of platinum, palladium and iridium in the heated solution; and adding a second metal salt into the solution including the metal seed. This method allows the production of uniform-sized nanoparticles under high concentration conditions in high yield and mass production in which the metal nanoparticles have high dispersion stability so that they are suitable for various application.
