【摘要】 采用二苯胺磺酸钠还原四氯合金酸的方法,在室温条件下,用SDS(十二烷基硫酸钠)、SDBS(十二烷基苯磺酸钠)作表面活性剂,成功地合成了金纳米粒子。分别讨论了还原剂二苯胺磺酸钠、表面活性剂(SDS、SDBS)及四氯合金酸的浓度等对金纳米粒子的粒径和形貌的影响。通过控制反应条件,可以合成出平均粒径大约为10、14、30、36nm的金纳米粒子。利用透射电镜(TEM)、紫外-可见(UV-Vis)吸收光谱对金纳米粒子进行了表征。研究结果表明不同的SDS或SDBS/HAuCl4的摩尔比,对金纳米粒子的尺寸大小有影响。更多还原

【Abstract】 Au nanoparticles have been prepared by the reaction of HAuCl4 and sodium diphenylamine sulfonate in the presence of SDS(sodium dodecyl sulfate)/SDBS(sodium dodecyl benzene sulfonate)at room temperature.Infection of varies of reactive conditions on the morphology and size of gold nanoparticles,such as the amount of the HAuCl4,reductant and SDS,was examined respectively.The average size of Au nanoparticles around 10,14,30 and 36nm can be obtained via controlling the reactive conditions,respectively.The nanoparticles were characterized by transmission electron microscopy(TEM),UV-Vis absorption spectrum.The research showed that the molar of SDS or SDBS/HAuCl4 has effect on the size of Au nanoparticles.更多还原
