无助剂合成纳米银线的制备方法综述

A review on synthesis methods of silver nanowires without auxiliary agents

迄今为止,银纳米线(AgNWs)可以常规合成。然而,没有任何添加剂的AgNWs的制备尚未达到类似的控制水平,其制备方法和控制机理一直是研究的重点和难点。在分析国内外近20年内40余篇相关文献的基础上,总结了无助剂直接合成AgNWs的制备方法和控制机理,主要包括多元醇法、晶种法、模板法、湿化学法、光还原法、电化学法和绿色合成法,并对上述方法的优缺点进行了总结分析与展望。

To date,silver nanowires(AgNWs)can be routinely synthesized.However,the preparation of AgNWs without any additives has not yet reached a similar level of control,and its preparation method and control mechanism have always been the focus and difficulty of research.Based on the analysis of more than 40 related literatures in the past 20 years,the synthetic methods and control mechanism employed to prepare silver nanowires without auxiliary agents are summarized,including polyol method,seeded method,template method,wet chemical method,photo-reduction method,electrochemical reduction and green synthesis method.Their advantages and disadvantages of the above methods are summarized,analyzed and prospected.
