采用离子液体法,以离子液体（DESs）为溶剂,柠檬酸三钠为还原剂,氯金酸为晶种,硝酸银为银源,制备了Ag/AgCl纳米枝状结构。利用SEM、XRD、EDS对样品的形貌、成分、结构进行了表征分析,并测试了样品的光催化性能。结果表明,当反应温度为160℃,反应时间为24h时,可获得完整的Ag/AgCl纳米枝状结构;枝状结构的形成是基于AgCl在还原剂作用下不断向Ag转换过程的结果;产物具有较好的光催化效果,并且随着反应时间的延长,产物的光催化性能减弱。

In this article, a novel surfactant-free method to synthesize Ag/AgCl dendrite nanostructures. In this method, we used DESs as solvent, sodium citrate as reducing agent, chloroauric acid as seed, silver nitrate as silver source respectively. The products were characterized by SEM, XRD, EDS and their photocatalytic property was measured. It was found that the perfect nanodendrites could be obtained at 160℃ after 24h reaction. The formation of final dendrite nanostructures can be explained by a trans-formation process from AgCl to Ag. Companying the increasing reaction time, the decrease of AgCl and increase of Ag could be found. Due to the presense of AgCl, the products have good photocatalytic performance.
