PREPARATION METHOD OF METAL NANO PARTICLE USING MICRO MIXER

摘要

A method for manufacturing metal nanoparticles is provided to cause a uniform reaction by improving a mixing efficiency and produce the metal nanoparticles having uniform size and shape. A method for manufacturing metal nanoparticles includes the steps of: (1) preparing a solution of metal salt and a strong reductant solution having a standard reduction potential of -0.23 V or less; and (2) mixing the solutions using a micromixer even without supplying separate heat energy from the outside and causing a reduction reaction of metal at the same time. The metal nanoparticles have a particle size of 20-200 nm. The metal is at least one selected from the group consisting of precious metals and transition metals.
