摘要: 报道了一种在不需光照的条件下制备三角形银纳米片的新方法.在表面活性剂BRIJ35存在下,将硝酸银用硼氢化钠和柠檬酸钠还原,在不同温度范围内反应形成各种尺度的三角形银纳米片,探讨了硼氢化钠浓度、BRIJ35浓度和表面活性剂的种类和溶液pH值等因素对银纳米颗粒形貌和尺寸的影响.

关键词: 银纳米片, 三角形, 化学还原, BRIJ35

Abstract: A new non-light chemical method was reported to prepare triangular silver nanoplates. In the presence of BRIJ35 molecules, nitrate silver was reduced by sodium borohydride and sodium citrate, resulting in triangular silver nanoplates with various sizes at different temperatures. Some other factors affecting the size and shape of silver nanoplates were studied such as the concentrations of sodium borohydride and BRIJ35, the kind of surfactants, and different pH values.

Key words: Silver nanoplates, Triangle, Chemical reduction, BRIJ35
