Microwave Hydrothermal Synthesis and Characterization of ZnO Nanostructures in Aqueous Solution
ZnO nanostructures were prepared in aqueous solution by microwave hydrothermal synthesis.XRD and FESEM were used to characterize ZnO nanostructures.The effects of pH,reaction temperature,and reaction time on yield of ZnO were investigated.The yield of ZnO was significantly increased with the increasing pH value,reaction temperature and reaction time.High yield and well crystallinity of ZNs was obtained at 120 ℃ for60 min with Zn/TEA=1∶1 by microwave hydrothermal synthesis.The spherical and rugby-like ZNs was obtained at 120 ℃ without TEA and,respectively.The concentration of Zn(OH)42-ions in the reaction solution and TEA had an important effect on the nucleation and morphology of ZnO nanostructures.Mechanism for the formation of ZnO nanostructures was proposed.
