“…In agreement with our results, Kong et al conducted a study on the photocatalytic degradation of MB using TiO 2 /ZnO nanocomposite and their results showed that this method can improve the optical properties of the ZnO nanoparticles for better photocatalysis of the target pollutants [36]. Luo et al [37] reported that the incorporation of silica into the structure of ZnO nanoparticles can improve their optical and electrical properties of the pure ZnO nanoparticles [37]. …”

A B S T R A C TOne of the major disadvantages of the application of ZnO nanoparticles as photocatalyst in photocatalytic systems is photoinstability due to the photocorrosion under UV light irradiation resulting in the significant reduction in their photocatalytic activity. Therefore, in the present study, SiO 2 nanopowders were incorporated into the ZnO nanoparticles to enhance their photocatalytic activity for the decolorization of methylene blue (MB) dye in comparison with pure ZnO/UV process. The efficiency of UV/ZnO/SiO 2 process was compared with UV/ZnO process for the decolorization of MB dye and the removal of chemical oxygen demand (COD). The effect of various amounts of SiO 2 (5, 10, and 15%) incorporated into ZnO nanoparticles was studied. At optimal SiO 2 loading of 10%, the decolorization efficiency of MB and the removal of COD were obtained to be 100 and 81%, respectively. However, using UV/ZnO process at the same operational conditions, the decolorization efficiency of MB and the removal of COD were 66 and 44%, respectively. An initial pH of 7 and initial dye concentration of 25 mg/L were chosen as optimal experimental conditions. It can be stated that the incorporation of SiO 2 nanopowders into the ZnO nanoparticles would be beneficial for enhancing their photocatalytic activity.

We report our study on the magnetic properties of Si-doped ZnO thin films fabricated by pulsed laser deposition technique. The Si-doped ZnO thin films show ferromagnetism at room temperature. The saturation magnetism increases from 0 to 2.4 emu/cc with the increasing of Si concentration up to 2%, and then decreases with further increasing of Si concentration. First-principles calculation demonstrates that the origination of ferromagnetism for Si-doped ZnO system is the two unpaired electrons of Si-2p. These unpaired electrons increase the magnetic moments which are responsible for the increasing ferromagnetism.

Abstract.(M x , Zn 1-x O), M= Sn, Al nanofibers properties were investigated. Pure and M-doped zinc oxide films were fabricated onto a glass substrate by a facile and low cost spin coating route. X-rays analysis reveals that films crystallize with a wurtzite structure according to (002) orientation. The transmittance in the visible range was as high as 88 % at 550 nm. The doping increased slightly the transmittance, the as-grown films were high transparent in VIS and IR ranges. The optical band gap was a little bit changed by doping. AFM 3D-views revealed that grains were nanofibers with the size of 18.22, 18.23 and 44.27 nm respectively for pure, Al and Sn-doped ZnO films.
