Beschreibung
Zusammenfassung:	The present invention relates to a method of synthesizing nano-sized metal and alloy nanoparticles by depositing metal and alloy nanoparticles having excellent uniformity of particle size on the surface of powder which is a parental material using a vapor deposition method, and melting the parental material by a solvent or heat, and to a production device thereof. More specifically, as an effective and inexpensive synthesizing method for solving a multiple and high-priced synthesizing method using chemical reduction reaction which is demerits of an existing method, provided are a method of synthesizing highly uniform sized metal, metal supported to alloy catalyst nanoparticles and carbon, and alloy catalyst nanoparticles and a production device thereof.
