Purpose-Built Anisotropic Metal Oxide Nanomaterials

Abstract

Large arrays of perpendicularly oriented anisotropic nanoparticles of ferric oxyhydroxide (Akaganeite, beta-FeOOH) and oxide (Hematite, alpha-Fe2O3) of typically 3-5 nm in diameter, self assembled as bundles of about 50 nm in diameter and of up to 1 micron in length have been successfully grown onto polycrystalline substrates without template and/or surfactant by heteronucleation from an aqueous solution of ferric salts and their optical and electronic properties investigated.
