Abstract

The present invention relates to a method for manufacturing metal nanoparticles containing rod-shaped nanoparticles, the method including: producing metal oxide nanoparticle intermediates having at least rod-shaped metal oxide nanoparticles by heating a mixture of a nonpolar solvent, a metal precursor and an amine including secondary amine at 60-300° C.; producing metal nanoparticles by adding a capping molecule and a reducing agent to the mixture and heating the result mixture at 90-150° C.; and recovering the metal nanoparticles. According to the present invention, the shape of metal nanoparticle can be controlled by mixing primary amines or secondary amines as proper ratio without using apparatus additionally, as well as, the size of metal nanoparticle can be controlled to several nm.
