  • Patent number: 11441232
    Abstract: A one dimensional (1D) nanoarray of SnO nanostructures on a substrate is disclosed. The nanostructures of SnO have diameters of 200 nm-1 ?m and lengths of 500 nm-3 ?m, and are attached to and substantially perpendicular to the substrate. The one-dimensional nanoarray may have a nanostructure density of 220-300 nanostructures per 100 ?m2 substrate and a band gap energy of 2.36-2.46 eV. The one-dimensional nanoarray may be formed by anodization of Sn foil in an electrochemical cell subjected to a voltage of 15-25 V for 1-3 hours at room temperature. The formed one-dimensional nanoarray may be used for the photo-electrochemical decomposition of water into O2 and H2.
