Claim:
1. A method for producing metal oxide nanowires, the method comprising: a. providing a reactor having: b. delivering a plasma-forming gas and a sheath gas to the dielectric tube via the plasma-forming gas inlet and the sheath gas inlet, respectively; c. applying a microwave energy to the plasma-forming gas in the dielectric tube to form a plasma; d. delivering a metal powder having a particle diameter of less than about 1 micron up to about 45 microns into the dielectric tube from the metal powder delivery system such that the metal powder reacts at temperatures close to the metal's melting point within the plasma along the longitudinal axis of the dielectric tube to produce metal oxide nanowires; and, e. collecting the metal oxide nanowires produced in Step d) in the product collector; wherein the metal oxide nanowire is defined as a nanoparticle having a first dimension and a second dimension wherein the first dimension is greater than the second dimension.
