“…The absorption band at 1640 cm -1 is due to δ(O-H) vibrations of the hydroxyl groups of some physically adsorbed water molecules, this is almost similar to the one at 1637 cm -1 reported δ(O-H) vibration [32]. The FTIR spectrum showed an absorption band at 465 cm -1 which is typically due to the lattice stretching vibrations ν(Zn-O) [6,33]. There were no new peaks were observed due to the use of surfactant in all samples, this implies that almost complete removal of surfactants was achieved by washing process.…”

ZnO NPs were prepared and deposited onto cotton fibers via ultrasound irradiation successfully. Different surfactants (SDS, HY, CTAB, TX-100) have been used to stabilize, homogenize the coated ZnO NPs and control their shape and size as encapsulated species. The use of surfactants has improved the durability of ZnO NPs and decreased its leaching in particular SDS. The small mean crystallite size for ZnO particles due to the use of surfactants is the main reason for decreasing the leached of ZnO particles from cotton substrate. SEM and XRD analysis revealed information about the shape and size of the coated ZnO nanoparticles. The use of SDS and HY surfactants in the synthesis of ZnO NPs coated fabrics showed the highest antibacterial and antifungal activities against different pathogenic bacterial and fungal species with high reduction reached over 90%.

“…The heterogeneous semiconductors can also be utilized to trap electrons at surface sites and to support the formation of superoxide anion radicals O 2 − from O 2 molecules. There are many methods which can be used for the preparation of heterogeneous metal oxide nanocomposites, including hydrothermal [12], chemical vapor deposition [13], sonochemical [14], and the sol-gel [15,16] method. Among these, the sol-gel method has several advantages, being more economical, requiring only a simple preparation, and having good stability and reproducibility [17].…”

The SiO2@α-Fe2O3/ZnO metal oxide nanocomposites employed in this study were obtained using the sol-gel method. Their photocatalytic activities were enhanced by photo-Fenton reactions. The metal oxide composite of ZnO and α-Fe2O3 nanoparticles were deposited on the SiO2 nanospheres intended for visible light photocatalysis. Further, the as-synthesized SiO2@α-Fe2O3/ZnO nanocomposites exhibited a robust crystallinity and a high adsorption of dye molecules when compared to SiO2@ZnO and SiO2@α-Fe2O3 nanocomposites, respectively. The experimental results demonstrated a rapid Methylene Blue (MB) degradation among these catalysts within short intervals of time with the addition of α-Fe2O3/ZnO mixed metal oxide catalysts on the SiO2 nanospheres. Finally, a photo-Fenton reaction was implemented to confirm the presence of the hydroxyl (OH) radicals, which are powerful agents used for the degradation of organic pollutants.

“…Various techniques have been used to grow micro and/or nanostructured ZnO surfaces according to the suitability of ZnO developed nanostructures for a particular application [18][19][20][21][22][23][24][25][26]. The techniques used to grow ZnO nanostructures based on the required growth temperature and complexity can be divided into three main categories: First, high-temperature (> 500 °C) thermal evaporation techniques such as metal-organic chemical vapor deposition, solid-vapor deposition, vapor-liquid-solid growth, and high pressure pulsed laser deposition.…”

In this report, superhydrophobic and highly oleophobicmicro-nano-scale roughened Zn sheet surfaces were obtained. A simple and environmentally friendly technique of immersing Zn sheets in hot deionized water was used to grow ZnO nanorods. Variation of the immersion time had a significant impact on the evolution and formation of the nanorods. After their concealing with long chain fluorocarbon oligomers of 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane (PFDTS), ZnO nanorod surfaces prepared at 60 min immersion time showed the highest wetting repellency properties toward water and peanut oil. However the surfaces yet to be able to super repel the two liquids. In order to improve the Zn sheet surfaces repellency toward liquids with various surface tensions, hierarchical structures with the combination of both micro channels covered-up with ZnO nanorods were developed. Simple technique of one-directional mechanical sanding was used to impart micro channeled structures onto Zn sheet surfaces and post immersion in hot de-ionized water for ZnO nanorods cover-up. The concealed micro-nano-combination structures with 1H, PFDTS oligomers showed superhydrophobic and highly oleophobic properties. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Photoluminescence (PL) techniques were used to characterize the morphology of the prepared surfaces.
