Nanocrystalline mercury chalcogenides HgE (E=S, Se, Te) were synthesized in a single step by a convenient, simple sonochemical method. Mercury nitrate, Hg(NO3)2, dissolved in 0.1 M ethylenediamine tetraacetic acid (EDTA), was used as the source of mercury and elemental chalcogenes, dissolved in a NaOH solution, as the sources of chalcogenide. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDAX). The synthesis procedure is simple and uses less toxic reagents than the previously reported methods. The results showed that the complexing agent EDTA plays a crucial role in the process.
通过一种简便的单步超声化学方法合成了纳米晶硫族汞化物HgE（E = S、Se、Te）。溶解于0.1 M乙二胺四乙酸（EDTA）中的硝酸汞Hg(NO3)2用作汞源，而溶解于NaOH溶液中的元素硫族元素用作硫族化物源。通过X射线粉末衍射（XRD）、透射电子显微镜（TEM）和能量色散X射线光谱（EDAX）对产物进行了表征。该合成过程简单，且使用的试剂毒性比先前报道的方法更小。结果表明，络合剂EDTA在该过程中起着至关重要的作用。
