在本次通讯中，我们报告了贵金属纳米粒子的一锅合成及其同时组装成有序纳米结构的方法。十二烷基硫酸钠（SDS）和三乙二醇单十二烷基醚（C12EO3）表面活性剂混合物形成高粘弹性流体，反映了长蠕虫状胶束的存在，该胶束可用作通过银和铂纳米颗粒的受控原位合成来制造有序纳米结构的模板。基于金属离子原位还原的简单而通用的方法为贵金属纳米粒子自组装重组结构的开发开辟了新途径。
In this communication, we report the one-pot synthesis of noble-metal nanoparticles and their concurrent assembly into ordered nanostructures. Sodium dodecyl sulfate (SDS) and triethylene glycol monododecyl ether (C12EO3) surfactant mixtures formed highly viscoelastic fluids, reflecting the presence of long, wormlike micelles which can be used as a template for making ordered nanostructures via a controlled in situ synthesis of silver and platinum nanoparticles. The simple and versatile approach based on in situ reduction of metal ions opens a new avenue for the development of self-assembled regimented structures by noble-metal nanoparticles.
