Growth of ZnO Nanostructures with Controllable Morphology Using a Facile Green Antisolvent Method

A facile green antisolvent approach to Cu2+-doped ZnO nanocrystals with visible-light-responsive photoactivities.

An environmentally benign antisolvent method has been developed to prepare Cu(2+)-doped ZnO nanocrystals with controllable dopant concentrations. A room temperature ionic liquid, known as a deep eutectic solvent (DES), was used as the solvent to dissolve ZnO powders. Upon the introduction of the ZnO-containing DES into a bad solvent which shows no solvation to ZnO, ZnO was precipitated and grow...

Sonochemical Green Method for Preparation of Mg-Doped ZnO Nanostructures in Water with Enhanced Photocatalytic Activity

In this work, Mg-doped ZnO nanostructures were prepared in water under ultrasonic irradiation for 60 min without using any organic compounds or post preparation treatments. The prepared samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive analysis of X-ray (EDX), diffuse reflectance spectroscopy (DRS...

A Facile Solvothermal Method for Synthesis of CuInS2 Nanostructures

CuInS2 nanostructures were  synthesized  via  a  simple  surfactant-free solvothermal  route.  In  this  synthesis,  thiosemicarbazide  and thioglycolic acid were used as sulfur sources. The effects of different parameters such as type of precursor and time on the morphology and particle  size  of  the  samples  have  been  investigated.  The nanostructures  were  characterized  by  means ...

Hydrothermal growth of ZnO nanostructures.

One-dimensional nanostructures exhibit interesting electronic and optical properties due to their low dimensionality leading to quantum confinement effects. ZnO has received lot of attention as a nanostructured material because of unique properties rendering it suitable for various applications. Amongst the different methods of synthesis of ZnO nanostructures, the hydrothermal method is attract...
