摘要/Abstract

摘要： 以氯金酸为原料制备出金种子,采用种子生长法,成功制备具有高指数晶面的二十四面体金纳米颗粒。首先,通过调节溶液中Au³⁺/抗坏血酸(AA)的摩尔比例,制备具有{331}、{441}和{431}高指数晶面的二十四面体金纳米颗粒。并利用高分辨透射电镜投影角度图及去卷积循环伏安曲线对这些纳米颗粒的表面晶面进行系统定性与定量分析。其次探讨溶液中十六烷基三甲基氯化铵(CTAC)浓度对二十四面体金纳米颗粒形貌的影响。结果表明,AA含量的增加显著促进了高指数晶面的形成,CTAC浓度的增加有助于提高纳米颗粒的单分散性。综上得,本研究实现了高指数晶面金纳米颗粒的可控合成,为后续在催化、传感及表面增强拉曼散射(surface-enhanced Raman spectroscopy, SERS)等领域的应用研究奠定基础。

Abstract: Gold seeds were prepared using chloroauric acid as raw material, and the seed growth method was used to successfully prepare trisoctahedralgold nanoparticles(TOH-Au NPs)with high-index crystal faces.Firstly, trisoctahedral gold nanoparticles with high-index facets of {331}, {441}, and {431} were successfully fabricated through a seed-mediated growth method by precisely controlling the molar ratio of Au³⁺/ascorbic acid(AA)in the reaction system. The surface facets of the as-prepared nanoparticles were systematically characterized using transmission electron microscopy(TEM)combined with projection angle analysis and deconvolution of cyclic voltammetry(CV)curves, which confirmed the successful formation of high-index facets. Furthermore, the influence of cetyltrimethylammonium chloride(CTAC)concentration on the formation of TOH-Au NPs was investigated. The results demonstrated that the increase of AA content significantly promoted the formation of high-index crystal planes and the increasing the CTAC concentration improved the monodispersity of the nanoparticles. This study provided a robust strategy for the controllable synthesis of gold nanoparticles with specific high-index facets, laying a solid foundation for their potential applications in catalysis, sensing, and surface-enhanced Raman spectroscopy(SERS).

Key words: gold nanoparticle, seed growth method, high index facet, deconvolution analysis, cyclic voltammetry curve
