Main methods for current production of metallic nanoparticles in different forms are reviewed. Metal nanoparticles are generally synthesized in form of nanopowders, nanowires, nanoclusters, nanorods, nanobelts, and nanofilms. Bi- and trimetallic clusters and alloys are also of an interest. Examined techniques for obtaining metal nanoparticles include chemical vapor and electrochemical deposition, use of γ-, X-ray, laser and UV-irradiation, ultrasonic and microwave treatment, electron- and ion-beams, arc discharge, decomposition and reduction of metal salts and complexes, and biosynthesis. A special attention is paid to Rieke and supported metals.
Keywords: Rieke metals, supported metals, metal nanoparticle, metal nanopowder, metal nanowire, “soluble” metal, nanoalloy, nanofilm
