This study demonstrates a novel approach for rapid synthesis of silver (Ag) nanowires induced by vanadium trioxide (V₂O₃) particles in aqueous solution at room temperature. Silver nanowires have an average diameter of 20 nm and length up to a few micrometers by parametric optimization. The micro-structure of the silver nanowires was characterized by TEM, HRTEM, SEM, and XRD techniques. The optical property of the as-prepared product was measured by ultraviolet–visible (UV–vis) spectroscopy. The possible growth mechanism of Ag nanowires via oriented attachment of Ag nanocrystals was discussed. The present approach shows several unique features such as rapid (a few minutes), reproducible and high-yield reaction with no need of any modifiers. V₂O₃ rods were reported for the first time to be used for synthesis of silver nanowires, playing multiple roles as reducing agent, template, and catalyst. The silver nanowires produced are promising for optical applications (e.g., SERS) due to their rough surface.

这项研究证明了一种在室温下快速合成由三氧化钒（V ₂ O ₃）颗粒诱导的银（Ag）纳米线的新方法。通过参数优化，银纳米线的平均直径为20 nm，长度可达几微米。银纳米线的微结构通过TEM，HRTEM，SEM和XRD技术进行了表征。所制备产品的光学性质通过紫外可见（UV-vis）光谱法测量。讨论了通过Ag纳米晶体的定向附着可能的Ag纳米线的生长机理。本方法显示出一些独特的功能，例如快速（几分钟），可重现和高收率反应，无需任何改性剂。V ₂ O ₃首次报道了用于合成银纳米线的碳棒，它们在还原剂，模板和催化剂中起着多种作用。所生产的银纳米线由于其粗糙的表面而有望用于光学应用（例如SERS）。
