Sonochemical synthesis of ZnO nanosheet
چکیده انگلیسی

ZnO nanosheets have been successfully synthesized by a sonochemical method under ambient air without any template. The prepared ZnO particles were characterized by powder X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was found that both high pH value and zinc salt counter-ion played critical roles for the formation of ZnO nanosheets. A plausible formation mechanism of ZnO nanosheets was discussed in detail.

ZnO nanosheets have been successfully synthesized by a sonochemical method under ambient air in alkali aqueous solution without any template. It is found that the morphology of ZnO powders prepared at pH 12.5 is rod-like and sheet-like. ZnO powder exhibited sheet-like shapes using ZnCl2 and ZnSO4 as zinc resources.Figure optionsDownload as PowerPoint slideSEM images of as-made ZnO powders prepared by sonochemical method using the mixture of different zinc salt and NaOH as precursor at pH 12.5: (a) ZnCl2; (b) ZnSO.
