Abstract Changes in nanostructure morphology and size may result very different surface wettability. In this research, the impact of morphological parameters on wetting dynamics ZnO nanostructured layers is studied. Six morphologies are chosen to determine specific processes nanostructures: nanoneedles, small diameter rods, large nanotubes, nanoplates, plain thin films. Wetting investigated usi...

UNLABELLED BACKGROUND The discharge of wastewater that contains high concentrations of reactive dyes is a well-known problem associated with dyestuff activities. In recent years, semiconductor photocatalysis has become more and more attractive and important since it has a great potential to contribute to such environmental problems. One of the most important aspects of environmental photocat...

Nanocomposite electrodes having three-dimensional (3-D) nanoscale architecture comprising of vertically aligned ZnO nanorod array core-polypyrrole (PPy) conducting polymer sheath and the vertical PPy nanotube arrays have been investigated for supercapacitor energy storage. The electrodes in the ZnO nanorod core-PPy sheath structure are formed by preferential nucleation and deposition of PPy lay...

Nanostructures made of zinc oxide (ZnO), a wide-bandgap semiconductor, have recently attracted attention due to their proposed applications in low-voltage and shortwavelength (368 nm) electro-optical devices, transparent ultraviolet (UV) protection films, gas sensors, and varistors. Raman spectroscopy presents a powerful tool for identifying specific materials in complex structures and for extr...

In the past decade the global research interest in wide band gap semiconductors has been focused on zinc oxide (ZnO) due to its excellent and unique properties as a semiconductor material. The high electron mobility, high thermal conductivity, good transparency, wide and direct band gap (3.37 eV), large exciton binding energy (60 meV) at room temperature and easiness of growing it in the nanost...

The interest in dye-sensitized solar cells has increased due to reduced energy sources and higher energy production costs. For the most part, titania (TiO2) has been the material of choice for dye-sensitized solar cells and so far have shown to exhibit the highest overall light conversion efficiency ∼ 11 %. However, zinc oxide (ZnO) has recently been explored as an alternative material in dye-s...

Nanostructures of zinc oxide (ZnO) are considered promising photocatalysts for the degradation organic pollutants in water. This work discusses an situ growth and UV photocatalytic effect ZnO nanostructures on a Zn plate immersed methylene blue (MB) at room temperature. First, surfaces were pretreated via sandblasting to introduce micro-scale roughness. Then, plates MB exposed light, observe na...
