| 摘 要： | 采用改进的Brust方法,用硼氢化钠还原氯金酸,并以巯基丁二酸(MSA)、氮乙酰基半光胺酸(NAC)作为包裹剂,成功制备了单分散的水溶性金纳米团簇。高分辨透射电镜(HRTEM)结果表明,增大硫醇与氯金酸的比例并增加氯金酸的初始浓度,有利于得到尺寸更小的金纳米粒子。当氯金酸的浓度(CAu)为9.3 mmol·L-1,CAu:CS为1:30时,得到了直径约为1 nm、标准偏差为0.2 nm的Au@MSA纳米团簇。结合紫外(UV)、热重(TG)和X射线光电子能谱(XPS)分析结果,可以推测出单分散金纳米簇的化学式为Au38(MSANa)26]或Au39(MSANa)27]。

| Abstract: | Monodispersed water-soluble gold nano-clusters were prepared by using sodium borohydride to reduce tetrachloroauric acid in methanol, with water-soluble 2-mercaptosuccinic acid as the protecting agent on gold nano-cluster surface. HRTEM results show that MSA monolayer-protected gold clusters were obtained with size of about 10.2 nm by increasing the proportion of 2-mercaptosuccinic acid and concentration of tetrachloroauric acid with CAu:CS=1:30. TG, UV and XPS results show that the possible chemical formula of the synthesized gold nano-clusters is Au38(MSANa)26] or Au39(MSANa)27]. |
