Abstract

A method of preparing a metal oxide nanostructure, the method including mixing a metal precursor solution with a basic solution to form a reaction mixture; and heating the reaction mixture in a closed container to provide a pressure greater than ambient pressure. Metal oxide nanostructures having a mean aspect ratio of at least about 4:1 and a cross-sectional width of about 100 nanometers or less are also disclosed.
