<p>A manufacturing method of metal nanoparticle is provided to obtain metal nanoparticles of even size in high density under non-aqueous condition in the absence of additional organic solvent. The manufacturing method of metal nanoparticle comprises steps of: preparing a mixture by dissociating a metal precursor in fatty acid; and adding salt of metal selected from a group consisting of Sn, Mg and Fe as a metallic catalyst into the prepared mixture. The metal precursor is a salt of metal selected a group consisting of Ag, Pd, Pt, Au and alloy thereof. The metal precursor is added in the amount of 0.01-1 mol per 1 mol of fatty acid. The fatty acid is selected from a group consisting of saturated fatty acid(CnH2nO2), oleic fatty acid(CnH2n-2O2), linoleic fatty acid(CnH2n-4O2), linolenic fatty acid(CnH2n-6O2) and highly unsaturated fatty acid(CnH2n-8O2, CnH2n-10O2, CnH2n-12O2). The metal catalyst is added in the amount of 0.001-0.5 mol per 1 mol of the metal precursor. The step of adding salt of metal comprises steps of: adding metallic catalyst while stirring the prepared mixture; and heating the mixture at 80-150deg.C for 0.5-4 hours. Optionally, polar solvent is added to the prepared mixture for precipitating nanoparticles.</p> |
