Zinc oxide (ZnO) nanocrystalline with different morphologies was successfully fabricated by solid-state reaction using aging Zn as precursor. Systematic experiments were carried out to investigate the factors that affect the morphologies of the samples. X-ray diffraction (XRD) spectrum shows that the as-prepared sample was hexagonal wurtzite structure. Scanning electron microscopy (SEM) images indicate that ZnO with different morphologies such as comb-like, tetrapod and flake structures, could be controlled by simply varying the ambient pressure, gas mixture ratio and growth temperature. The gas sensitivity properties of ZnO nanocrystalline thin films are investigated by observing the change of capacitance and conductance with a planar capacitor. It is found that the comb-like ZnO thin film sensor exhibits high sensitivity and fast response to ethanol at 150 °C.

One Step

A simple and facilitate method was reported to synthesize zinc oxide and lead oxide nanorods. Two metal oxides nanorods were directly obtained from grinding solid metallic salts and sodium hydroxide in agate mortar with the assistance of a suitable surfactant in only one step, which is different from the results of hydroxides in solution. The as-prepared products were characterized by XRD, TEM and SEM. An explanation describing possible mechanism for the rod-formation is given.

The nanostructural zinc oxide (ZnO) particles have been synthesized by two techniques, solid-state reaction and solvothermal method. The solid-state reaction method, the ZnO nanoparticles were carried out by reacting zinc acetate with sodium hydroxide in sodium dodecyl sulfate (SDS) and beta-cyclodextrin (b-CD). The effects of reaction condition on the nanocrystal morphology were investigated. The physical properties of ZnO were characterized using X-ray diffraction technique and transmission electron microscopy. The results showed that the obtained ZnO nanorods were in the wurtzite structure with various sizes of single crystals. FT-IR analysis also confirmed the binding of SDS with ZnO nanorods. For the solvothermal technique, ZnO nanostructures with various morphologies were synthesized from the treatment of zinc acetate at 80°C with the selected polymeric surfactant, poly(vinyl pyrrolidone) (PVP), in aqueous solution and ethylene glycol. The results showed that the selected surfactant and solvent play a different role in controlling the morphologies of the ZnO nanocrystals. The ZnO nanorods and nanoparticles were successfully obtained. The XRD result revealed that the ZnO is in the wurtzite structure with the particle size in range of 270-1300 nm. The optical properties of the samples were also studied via UV-vis spectrophotometer.
