In the present study, composite layer double hydroxide-metal oxide (Ni/Al-TiO2 and Ni/Al-ZnO) was successfully prepared used as catalyst of oxidative desulfurization dibenzothiophene. Characterization XRD, FTIR, SEM-EDS. The structure Ni/Al-LDH, TiO2, ZnO in Ni/Al-TiO2 Ni/Al-ZnO consistent, which also indicated that preparation did not change form precursors. FTIR spectra absorption band at 339...

ZnO can be made into many nanostructures that have unique properties for advanced applications. This Letter reports a process to synthesize ZnO nanorods in a counterflow diffusion flame reactor. Unlike the previous work on flame syntheses, our work shows that pure ZnO nanorods can be made in a freestanding form. It was demonstrated that ZnO nanorods with different aspect ratios can be obtained ...

Based on a novel Al-doped ZnO thin film/ZnO single crystal system, the effects of interface electric field on photocatalysis were investigated in detail. Both the position and intensity of the electric field are found to have decisive influence on the photocatalytic activities.

The microstructure and micro-composition of ZnO thin films doped with Al, deposited on Si/SiO2 substrates by sol-gel method were investigated by scanning and high resolution transmission electron microscopy and related energy dispersive X-ray analyses (SEM-EDX, STEM-HRTEM/EDX). Thin films of ZnO were prepared by deposition of 1-10 successive layers with 0.5 at.% and 5 at.% Al concentrations. Th...

A critical part of thin-film composite solar cells is conduction through the transparent electrode. Currently the material of choice for the window electrode is indium tin oxide (ITO). The natural abundance of indium however is insufficient for highvolume production of solar cells. Moreover, good quality ITO is made by expensive vapor-deposition processes. We propose to develop nanostructured d...

Reactively sputtered ZnO thin film gas sensors were fabricated onto Si wafers. The atmosphere dependent electrical response of the ZnO micro arrays was examined. The effects of processing conditions on the properties and sensor performance of ZnO films were investigated. Using AFM, SEM, XRD and WDS, the O2/Ar ratios during sputtering and Al dopant were found to control the property of ZnO films...
