在表面活性剂三甲基溴化铵(CTAB)存在下,采用二种四异丁基间苯二酚[4]芳烃作为还原剂在无水乙醇或去离子水中于120℃反应8h合成出银纳米粒子。调整反应参数,特别是CTAB与[Ag(NH3)2]+的浓度比,会形成银不同的纳米结构,包括球形和菱形。把表面活性剂改为十二烷基苯磺酸钠(SDBS)可以生成银纳米粒子(Nps)。分析了银纳米粒子的中间体和反应机理,结果表明溶剂热法是合成各种银纳米结构的一种有效和绿色的合成方法。
In the presence of the surfactant trimethylammonium bromide (CTAB), two kinds of tetra-isobutylresorcinol [4] arene were used as the reductants to react with each other in absolute ethanol or deionized water at 120 ℃ for 8h to synthesize silver Nanoparticles. Adjusting the reaction parameters, especially the concentration ratio of CTAB to [Ag (NH3) 2] +, will result in different silver nanostructures, including spheres and diamonds. Changing the surfactant to sodium dodecylbenzenesulfonate (SDBS) yields silver nanoparticles (Nps). The intermediates and reaction mechanism of silver nanoparticles were analyzed. The results show that solvothermal method is an effective and green synthesis method for synthesizing various silver nanostructures.
