摘要
利用绿色的、稳定的巯基功能化室温离子液体作为稳定剂,在室温条件下制备出相当稳定的Au纳米粒子.对制备的金粒子用紫外可见吸收光谱、透射电子显微镜和X-射线衍射进行了表征.结果表明在555nm处有强而锐的吸收峰并且金粒子的平均直径为2~3nm,X-射线衍射结构表征进一步说明产物是纳米级立方面心的单质金.
Gold nanoparticles has been synthesized by using environmentally friendly and stable thiol-functionalized ionic liquid as stabilizer at room temperature. The materials obtained are characterized by UV-Vis spectroscopy,TEM and XRD. The results demonstrate that the maximum absorption band is located at 555 nm and the average diameter of gold nanoparticles is in the range of 2-3 nm. XRD result further indicates the product is face-central cubic nanosized gold.
