| Abstract: | Shaped silver nanoparticles with like-spheres and dendrites have been prepared by sonoelectrochemical method from an aqueous solution of AgNO 3 in the presence of ethylenediaminetetraacetic acid disodium salt (EDTA). The silver nanoparticles are characterized by using powder X-ray diffraction (XRD) and transmission electron microscope (TEM). A typical XRD pattern of the as-prepared silver nanoparticles shows the presence of the diffraction peaks corresponds to the (111), (200), (220), (311) planes. All the peaks in the XRD pattern can be indexed as a fcc structure (JCPDS, No.4-0783). The effects of electrolysis on particle shapes are also discussed. It is found that the concentration of AgNO 3 and EDTA affects greatly the shape of the nanoparticles. |
