“…The introduction of nitrogen using micro-emulsion method increased the optical properties and activity of ZnO nanospheres [32]. In addition, several studies concluded that the addition of aluminum and iron as dopants inside ZnO structures converted their transparent thin films to be useful for photocatalytic applications and solar cells [33][34][35][36][37][38]. This positive effect of the addition of aluminum inside zinc oxide was confirmed by our previous research [7].…”

Water pollution and deficient energy are the main challenges for the scientific society across the world. In this trend, new approaches include designing zinc oxide nanohybrids to be very active in sunlight. In this line, organic and magnetic species intercalate among the nanolayers of Al/Zn to build inorganic-magnetic-organic nanohybrid structures. A series of nanolayered and nanohybrid structures have been prepared through intercalating very fine particles of cobalt iron oxide nanocomposites and long chains of organic fatty acids such as n-capric acid and stearic acid inside the nanolayered structures of Al/Zn. By thermal treatment, zinc oxide nanohybrids have been prepared and used for purifying water from colored pollutants using solar energy. The optical measurements have shown that the nanohybrid structure of zinc oxide leads to a clear reduction of band gap energy from 3.30 eV to 2.60 eV to be effective in sunlight. In this line, a complete removal of the colored pollutants (naphthol green B) was achieved after ten minutes in the presence of zinc oxide nanohybrid and sunlight. Finally, this new approach for designing photoactive nanohybrids leads to positive results for facing the energy- and water-related problems through using renewable and non-polluting energy for purifying water.

ZnO thin film deposited on the glass substrate at various substrate temperature by spray technique using perfume atomizer. The deposited ZnO thin films are annealed at 450ºC. The deposited films are highly transparent and adhered to the substrate. The structure and microstructural, morphological, compositional, optical and luminescent characteristics were studied by X-ray diffraction (XRD), Raman, Field emission scanning electron microscope (FE-SEM with EDX), Atomic force microscope (AFM), Ultra violet visible spectrophotometer (UV-Vis) and photoluminescence spectroscopic techniques. The crystalline nature of annealed film were confirmed from XRD and the shows preferred orientation along (1 0 1) plane. At higher substrate temperature, reorientation of planes was seen. The spherical shaped grains are observed from morphological studies. The roughness of ZnO film, one of the key parameter obtained from AFM, increases with substrate temperature. The high transparency of about 80% in visible region are obtained for ZnO film with band gap ranging from 3.24 – 3.19 eV. The presence of defects in ZnO films are identified from PL bands. The electronic vibrations in ZnO film were understood from Raman spectra. The weak ferromagnetic behavior at room temperature is observed and exchange interactions stemming from oxygen vacancy produce BMP and subject to RTFM in ZnO.

Energy and water related problems have attracted strong attention from scientists across the world because of deficient energy and water pollution. Following this line, new strategy depended on preparing nanolayers of Al/Zn and magnetic nanoparticles of cobalt iron oxides nanocomposite in addition to long chains of hydrocarbons of stearic acid to be used as roofs, fillers and pillars; respectively, to design optical-active nanohybrids in sunlight for removing the colored pollutants from water in few minutes. By using long chains of hydrocarbons of stearic acid, X-ray diffraction (XRD) results and TEM images showed expansion of the interlayered spacing from 0.76 nm to 2.02 nm and insertion of magnetic nanoparticles among the nanolayers of Al/Zn. The optical properties and activities showed that the nanohybrid structure based on zinc oxide led to clear reduction of the band gap energy from 3.3 eV to 2.75 eV to be effective in sunlight. Photocatalytic degradation of the dye of acid green 1 confirmed the high activity of the prepared zinc oxide nanohybrids because of a complete removal of the dye after ten minutes in sunlight. Finally, this strategy was effective for producing photo-active nanohybrids for using renewable and non-polluting energy for purifying water.
