Abstract:
A method of preparing a nanowire, comprising the steps of:providing at least one composition selected from the group consisting of: a metal composition, a metal oxide composition, end combinations thereof, wherein the metal of the metal composition and the metal of the metal oxide are selected from one group consisting of: tin, chromium, iron, nickel, silver, titanium, cobalt, zinc, platinum, palladium, osmium, gold, lead, iridium, molybdenum, vanadium, and aluminum; exposing the composition to thermal conditions of about 800Â° C. to about 1500Â° C. and at a pressure from about 200 to 650 Torr; vaporizing the composition while flowing an inert gas over the composition; and forming a metal oxide nanowire via a condensation reaction under non-catalytic conditions.
