Abstract
The potential applications of one-dimensional nanostructured materials widely depend on their shape and size. This paper deals with a method for synthesizing and characterizing silver nanowires through an organic solution. The so-called polyol method was used to synthesize silver nanowires in which ethylene glycol was used as both media and the reducing agent. Adequate CuCl2/ethylene glycol solution is used to prohibit chemical etching by the oxygen on nanowires surfaces. The effects of CuCl2 concentration and the addition rate of AgNO3 were examined. It was revealed that by optimizing the parameters, silver nanowires with aspect ratios of up to 32 are accessible. To characterize the structure and morphology of nanowires, X-ray powder diffraction, UV–Vis spectroscopy, scanning electron microscopy and atomic force microscopy were used.
Highlights
Presenting a straightforward method for synthesizing nanostructured materials is becoming a hot area of research because of their potential applications in optic, electronic and magnetic devices [1,2,3,4,5]

Introducing Cl- ions helps to reduce the concentration of free Ag? ions in the solution through the formation of AgCl nanocrystallites [note that Ksp (AgCl) ( Ksp (AgNO3)]
Summary
Presenting a straightforward method for synthesizing nanostructured materials is becoming a hot area of research because of their potential applications in optic, electronic and magnetic devices [1,2,3,4,5]. Polyvinylpyrrolidone (PVP) acts as a capping agent that blocks the {100} planes of the formed multiply-twinned particles (MTPs), helping the formation of silver nanowires. In such self-seeding process, the products may face some problems such as non-uniformity. The addition of trace amounts of salts to the polyol synthesis of metal nanostructures has been shown to influence the morphology of the resulting material. Korte et al [11] introduced a salt-mediated polyol method to overcome the non-uniformity of the silver nanowires. Korte et al [11] concluded that Fe(II) and Fe(III)-containing salts facilitate the growth of one-dimensional Ag nanostructures. The aim of present work was to identify the interactive role of these two factors in the growth mechanisms of silver nanowires
