METHOD OF PRODUCING METAL NANO-PARTICLES

摘要

PURPOSE: A manufacturing method of metallic nano-particles is provided to inject a metal precursor solution and a reduction solution into a reaction solution all at once and to mix the metal precursor solution and the reduction solution. CONSTITUTION: A manufacturing method of metallic nano-particles comprises the following steps. A reaction solution is made by adding a reduction solution to a dispersion solution. The reductant solution is added to the dispersing agent solution, and the reaction solution is manufactured. A metal precursor solution and the reductant solution are injected into the reaction solution all at once, and mixed together. The reaction solution of pH 9-13 is made by adding the reductant solution to the dispersion solution. The dispersing agent of the dispersion solution is selected among polyvinylpyrrolidone (PVP), cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate (SDS), and sodium carboxymethyl cellulose (Na-CMC).
