成核剂中不同金属阳离子对银纳米线可控合成的影响
Effect of Different Metal Cations in Nucleating Agents on Controllable Synthesis of Silver Nanowires
摘要
Abstract
This study investigated the significant effects of four typical metal cations,namely K+,Ca2+,Na+,and Mg2+,as nucleating agents on the synthesis of silver nanowires(AgNWs)using a polyol method.The structure and morphology of synthesized AgNWs were characterized by field emission scanning electron microscopy(SEM),ultraviolet-visible spectroscopy(UV-Vis),X-ray diffraction(XRD),and transmission electron microscopy(TEM).The impact of these four cations,which ranked high in terms of metal reactivity,on the controlled release of Ag+and their influence on the variations in morphology observed in formed AgNWs were discussed.The results indicated that cations of highly reactive metals had a greater impact on the high purity of AgNWs.This work presented a simple,effective,and controllable method for producing highly pure AgNWs with different aspect ratios.关键词
