Randomly Oriented Rectangular Shaped Structures Of CuO On NiO/ITO Surfaces

Metal oxide materials are one of the promising materials for low power consumption devices due to their unique size and dimensionality dependent physical and chemical properties. Low cost of production is also a key component in micro/nanoscale devices. Cupric oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in solar cells, bio and gas sensors, batteries, super capacitors, catalysis, photo detectors, energetic materials and removal of organic pollutants from waste water. An attempt has been made to synthesize randomly oriented rectangular shaped nanostructures of CuO, via hydrothermal synthesis at low temperature (~70 °C) on top of NiO porous structured film. The film was deposited using chemical bath deposition method at room temperature using ITO coated glass plate as a substrate. One can observe that the CuO growth on NiO/ITO substrate not only filled the porous structures of NiO but also formed the long rectang
