| 摘 要： | 以Cyanex 301萃取剂为硫源，分别萃取Ag+和Cu2+，两相热法制备了Ag2S纳米颗粒和CuS微结构，采用X射线粉末衍射、紫外可见光谱、红外光谱以及电子显微镜对产物进行了表征。 表明制得的Ag2S和CuS分别为单斜相和六方相。 产物粒径随着反应温度的升高而增大，因而可通过加热温度调控产物尺寸，另外还考虑了其它反应条件对产物的影响。

| Abstract: | Monoclinic Ag2S nanoparticles and hexagonal CuS microstructures have been successfully prepared from solvent-extraction systems by a two-phase thermal method.In these systems,the extractant Cyanex 301(di-(2,4,4-trimethylpentyl) dithiophosphinic acid) acts as not only the surfactant but also the sulfur source.The products were characterized by powder X-ray diffraction(XRD),UV-Visible spectroscopy(UV-Vis),FT-infrared spectroscopy(FTIR) and transmission/scanning electron microscopy(TEM/SEM).It is found that th... |
