Abstract
A method of forming a one-dimensional nanoarray of In2O3 nanowires on indium foil is disclosed. The nanowires of In2O3 have diameters of 30 nm-50 nm and lengths of 100 nm-200 nm, and are attached to and substantially perpendicular to the surface of the indium foil. The In2O3 nanoarray may have a nanowire density of 200-300 nanowires per μm2 indium foil and a band gap energy of 2.63-3.63 eV. The In2O3 nanoarray may be formed by anodization of indium foil in an electrochemical cell subjected to a voltage of 15-25 V at room temperature.
