摘要:

简要综述了使用一价金复合物AuCl(油胺)作为前驱物合成形貌可控的金纳米结构的相关工作. 通过改变有机溶剂、添加异质金属纳米粒子及控制反应温度等手段, 成功合成出球形的金纳米粒子(平均直径12.7 nm)、超细金纳米线(平均直径1.8 nm)及超细金纳米棒(平均直径2 nm); 并通过牺牲磁性纳米粒子模板的方法合成出枝状金纳米结构. 除了对合成方法和过程的介绍, 还简要讨论了每种纳米结构的形成机制.

Abstract:

This review article briefly discusses the use of AuCl(oleylamine) complex as a precursor in the facile synthesis of gold nanostructures with controlled morphologies. By controlling the solvent, the added metal nanoparticles, and the reaction temperature, we have successfully prepared spherical gold nanoparticles with an average diameter of 12.7 nm, ultrathin gold nanowires with an average diameter of 1.8 nm, and ultrathin gold nanorods with an average diameter of 2 nm. Gold multipod nanostructures have also been prepared by templating against a self-destructive template of magnetic nanoparticles. In addition to the synthetic protocols, this article also provides a brief account of the mechanismresponsible for forming each type of gold nanostructure.

Key words: Gold, Nanostructure, AuCl(oleylamine) complex
