Zinc oxide can be called a multifunctional material thanks to its unique physical and chemical properties. The first part of this paper presents the most important methods of preparation of ZnO divided into metallurgical and chemical methods. The mechanochemical process, controlled precipitation, sol-gel method, solvothermal and hydrothermal method, method using emulsion and microemulsion enviroment and other methods of obtaining zinc oxide were classified as chemical methods. In the next part of this review, the modification methods of ZnO were characterized. The modification with organic (carboxylic acid, silanes) and inroganic (metal oxides) compounds, and polymer matrices were mainly described. Finally, we present possible applications in various branches of industry: rubber, pharmaceutical, cosmetics, textile, electronic and electrotechnology, photocatalysis were introduced. This review provides useful information for specialist dealings with zinc oxide.

“…Zinc oxide can occur in one-(1D), two-(2D), and threedimensional (3D) structures. One-dimensional structures make up the largest group, including nanorods [22,23], -needles [24], -helixes, -springs and -rings [25], -ribbons [26], -tubes [27][28][29], -belts [30], -wires [31], -combs [32], and so forth; 1D structures were synthesised by Shouli et al [33]. The same authors obtained three different morphological forms of zinc oxide, namely needles, pencils, and flowers, in the process of hydrothermal precipitation in the presence of CTAB and SDS.…”

Zinc oxide was obtained by precipitation in an emulsion system with zinc acetate used as a precursor of ZnO and potassium hydroxide or sodium hydroxide as a precipitating agent. The cyclohexane, as an organic phase, and a nonionic surfactant mixture were also used for preparation of the emulsion. By applying modifications of the ZnO precipitation process, such as changing the precipitating agent, composition of substrates, and the rate of substrate dosing, some interesting structures of ZnO particles were obtained. The morphology of the modified samples was analysed based on SEM (scanning electron microscope) and TEM (transmission electron microscope) images. Moreover the samples were characterised by determination of their dispersive properties using the noninvasive back scattering method (NIBS), adsorption parameters (BET), and crystalline structure (XRD). Thermogravimetric analysis (TG) as well as infrared spectrophotometry (FT-IR) was also applied. For selected samples their electrical properties (dielectric permittivity and electric conductivity) were also measured. The zinc oxide obtained consisted of particles in the shapes of solids, ellipsoids, rods, and flakes, with size ranging from 164 to 2670 nm and showed well-developed surface area with values as high as 20 m2/g.

“…As known, the application of nanomaterials depends not only on their properties but also on their junction with other elements of a system. Very recently, a convenient method for the direct and large-area growth of 1-D ZnO nanostructures on a conductive brass substrate has been developed in our group, consisting of thermal oxidation of a Cu 0.66 Zn 0.34 alloy foil in the presence of oxygen. Various 1-D nanostructures such as nanowires, nanobelts, nanocombs, and nanosheets have been in situ grown on the brass substrate under different reaction temperatures.…”

Structural Regulation and Optical Properties of One-Dimensional ZnO Nanomaterials in Situ Grown from and on Brass Substrates

One-dimensional ZnO nanostructures have been in situ grown on the conductive brass substrate by directly heating the Cu0.70Zn0.30 alloy foils in O2/Ar at 550−900 °C. The growth process and products have been well characterized by means of X-ray diffraction, Raman scattering, electron microscopy, X-ray photoelectron, and photoluminescence spectroscopy. The results indicate that more Zn species is lost from the brass foils at the higher temperatures. Zn species is exhausted, and a sharp diffraction peak shift appears around 750 °C due to the quick depletion. The structures of the ZnO products have been systematically regulated and the more oxygen vacancy is associated with the higher reaction temperature. The correlation in between the oxygen vacancy concentration and the green and exciton emission for these products has been experimentally demonstrated and well understood, which is important for luminescence applications.
