ABSTRACT:
The present invention is directed to a process for making nanoparticles of metals, metal alloys, metal oxides and multi-metallic oxides, which comprises the steps of reacting a metal salt dissolved in water with an alkali metal salt of C4-25carboxylic acid dissolved in a first solvent selected from the group consisting of C5-10aliphatic hydrocarbon and C6-10aromatic hydrocarbon to form a metal carboxylate complex; and heating the metal carboxylate complex dissolved in a second solvent selected from the group consisting of C6-25aromatic, C6-25ether, C6-25aliphatic hydrocarbon and C6-25amine to produce the nanoparticles.
