摘要:
常温下HEPES缓冲溶液可还原HAuCl4的水溶液直接制备纳米金溶胶.当加入分散剂聚乙烯吡咯烷酮(PVP)或聚乙二醇(PEG),可得到形貌大小不同的纳米金颗粒.通过X射线衍射,透射电镜以及选区电子衍射等手段对其进行了表征,并利用紫外可见光谱研究了纳米金颗粒形成的反应动力学.结果表明:在常温下搅拌几分钟就可以得到纳米金颗粒,并且表面活性剂对纳米金颗粒的形貌和大小起着重要的作用.
Abstract:
Gold nanoparticles with different morphologies and sizes were obtained in HEPES buffer solution in the absence and presence of surfactants(polyvinylpyrrolidone and poly(ethylene glycol))at room temperature.These nanoparticles were characterized by Xray diffraction(XRD),transmission electron microscopy(TEM)and selected area electron diffraction(SAED).The kinetics of the formation of gold nanoparticles in HEPES buffer was studied by UVvisible spectrophotometer.Gold nanoparticles could be obtained easily at room temperature with continuous vigorous stirring.The surfactants play a crucial role in the size and shape controlled synthesis of gold nanoparticles.
