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),FTinfrared spectroscopy(FTIR) and transmission/scanning electron microscopy(TEM/SEM).It is found that the size of Ag₂S nanoparticles becomes bigger with the increasing temperature and the morphology and size of CuS microstructures can be controlled by the feed concentration or temperature.
