Simple non-basic solution route for the preparation of zinc oxide hollow spheres

Arrays of zinc oxide (ZnO) micro/nano pillars have been synthesized on indium-tin-oxide (ITO) substrates by a solution route under an external electric current. They were pillar-like morphologies and grew along the c-axis. Some comparative experiments showed that applying the external electric current effectively improved the alignment of the product in a short time. It was indicated that the micro/nano pillars can be obtained in a short time under an external electric current.

Nano Rods

Novel superstructures of zinc oxide thin film with nano-rods and nano-screws were prepared via soft solution route without any polymer additives. The thin film of ZnO could be produced directly on the substrates. The yield of nano-rod and/or nano-screw was almost 100%. Small amount of nano-disk superstructure was also obtained. The superstructures of the film changed depending on the kind of treatment organic solvent such as methanol, butanol, i-propanol, hexane, etc. Monodispersed or symbiotic/multipod ZnO nanorods with hexagonal cross section or screw microstructure were successfully prepared.

Chemical Solution Route

The monodispersed zinc oxide nanowires with lateral dimensions as thin as 20 nm and lengths up to 2 μm have been synthesized in a simple organic solution by using hydrothermal method. Particularly, these zinc oxide nanostructures has been prepared into single-crystalline prisms or belts with uniform diameters along the entire length. The structure and characteristic of the as-obtained ZnO nanostructures were confirmed by XRD, TEM, HRTEM, and EDX. UV measurements and photoluminescence had been used to characterize the optical properties and confirm the crystal perfection of these ZnO nanomaterials.

Structural Characterizations

A solution route has been developed to synthesize covellite (CuS) nanostructures through the precitation reaction of CuCl2 · 2H2O, thiourea (Tu), and NaHCO3 in distilled water at room temperature. By regulating the concentration of Tu, CuS nanotubes and hollow nanospheres with diameters of 100–200 nm have been selectively prepared. Structural characterizations indicate that both nanotubes and hollow spheres are composed of CuS nanoparticles with diameters of about 5–10 nm. UV-Vis absorption and room temperature photoluminescence (PL) spectra display different morphology-related absorption phenomena for nanotubes and hollow nanospheres. A systematic investigation has been carried out to understand the factors influencing the CuS morphology. Two different routes are identified to explain the formation of the nanotubes and hollow nanospheres herein.
