N-乙烯基吡咯烷酮可控合成多形貌金纳米颗粒

摘要

为了探究在N-乙烯基吡咯烷酮（NVP）体系下其对金纳米颗粒形貌的影响，分别在不同的操作条件下进行了金纳米颗粒合成实验，并通过TEM、UV-vis、XRD等手段对合成的金纳米颗粒进行了表征分析。随后，以三角片状金纳米颗粒为例对合成机理进行了探讨。结果表明：N-乙烯基吡咯烷酮不仅可以同时作为还原剂和稳定剂制备出能够稳定存在的金纳米颗粒，而且还能够诱导金纳米颗粒发生非均向生长，产生三角形和六边形金纳米片。在此发现的基础上，针对不同反应条件对该体系制备金纳米颗粒的影响进行了全面系统的实验研究，发现该方法还能制备出棒状和带有支脚的金纳米颗粒。

Abstract：

In order to investigate the variation tendency of the morphology of gold nanoparticles in the N-Viny-Pyrrolidone (NVP) system, gold nanoparticles were synthesized under different operating conditions and the morphology were characterized and analyzed through TEM, UV-vis and XRD. As an example, the synthesis mechanism of triangular gold nanoparticles with NVP was studies. The results show that stable gold nanoparticles can be obtained using NVP as reductant and stabilizer, and NVP can induce non-isotropic growth of gold nanoparticles, which created the triangular and hexagonal gold nanodisks. Besides, the effect of reaction condition on the synthesis of gold nanoparticles was studied. Rod-shape gold nanorods and nanoparticles with support also can be synthesized in this system.
