Synthesis of silver nanowires by a sonoelectrochemical method

A novel method for the preparation of silver nanowires without any template is presented via a sonoelectrochemical route in an aqueous solution containing silver nitrate and ethylenediamine tetraacetic acid (EDTA) under N2 atmosphere. The electrolysis was carried out with controlled-current and controlled-potential, respectively. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SEAD). Almost uniform silver nanowires were observed in the TEM images. An SEAD revealed the silver nanowires with single crystalline nature.
