Method for producing metal oxide nanorods, metal oxide nanorods and composite material containing these nanorods thus obtained

摘要

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.
