A Novel Method for the Production of a Vast Array of Metal, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

摘要

In this paper we discuss the materials that can now be produced using a novel method for producing high-purity metal, metal oxide, and mixed-metal oxide particles. The particles formed are uniform in size with dimensions that can range from 1 nm to greater than 10 im, The metal oxides produced by this method include (but are not limited to) the transition metals, rare earth metals, and the Groups I, II, and III metals of the Periodic Table. Mixed-metal oxides of any combination of the aforementioned metals with any stoichiometry can also be produced Additionally, the final oxidation state of the metal can be controlled. The present method is unique and advantageous because it uses a simple process to prepare large quantities of a vast array of metal oxides, mixed metal oxides, and metals with purity levels as high as 99.999+% with tight control of the particle size (±10%) This method is also much lower in cost and more environmentally benign than other techniques currently available.
