Abstract: A method for the synthesis and manufacture of metal nanoparticles using metal inorganic salts. The method is simple and uses inexpensive chemicals. The procedure produces nanometals in 100% yields. Method is scalable and produces nanoparticles in unlimited quantities. In this method, a metal inorganic salt is dissolved in a reaction medium, comprised of a solvent and organic amine to create a metal/amine complex. A reducing agent, comprised of a solvent and Sodium Borohydride (NaBH4), is then mixed with the metal/amine complex through titration or through a continuous flow process. The resulting nanoparticles are then precipitated through the addition of methanol and centrifugation and decanted. The decanted nanoparticles can then be suspended in a solvent for storage.

Abstract: A method and apparatus for producing surface stabilized nanometer-sized particles, the method including the steps of forming the aerosol by mixing reactants, a surface-stabilizing surfactant, and a liquid to form a mixture, forming a mist of droplets of the mixture, heating the droplets to cause a reaction between species of the mixture and collecting the nanometer-sized products. The method for producing various size, shape and size distribution of nanoparticles by changing the ratio of the reagents and the ligands in the mixture of precursors.
