Abstract:
1. A method for synthesis of a metal oxide nanomaterial, the method comprising the steps of: selecting a metal substrate; creating a non-equilibrium gas comprising oxygen plasma at a low temperature at the point of the surface of the metal substrate of between about 50° C. and the temperature of the boiling point of the metal substrate; exposing said metal substrate to said oxygen plasma having a neutral oxygen atom density of at least about 1×10 forming the nanomaterial comprising a metal oxide nanostructure from the metal oxide on the surface of said metal substrate; and controlling and maximizing the growth rate of said metal oxide nanostructure on said metal substrate by optimizing the density of said neutral oxygen atoms in said oxygen plasma.
