Abstract
Methods of preparing metal oxide nanorods are described. The metal oxide nanorods have diameters between 1 and 200 nm and aspect ratios between 5 and 2000. The methods include the steps of generating a metal vapor in a furnace, exposing the nanorod growth substrate to the metal vapor within a growth zone in the furnace for a sufficient time to grow metal oxide nanorods on a surface of the nanorod growth substrate, removing the nanorod growth substrate from the growth zone after the sufficient time to grow metal oxide nanorods on a surface of the nanorod growth substrate, and removing the metal oxide nanorods from the furnace. The methods can be used to prepared large quantities of metal oxide nanorods.
