摘　　要：以适量的月桂酸硫脲咪唑啉季铵盐(SUDEI)为表面活性剂,采用溶剂热法在N-N二甲基甲酰胺(DMF)/乙醇中160℃反应12 h,制备出了单分散的直径约300 nm左右的纳米MnS空心球,并采用TEM、SEM观察其形貌;X射线衍射测试其晶体形态;IR、EDS测试其结构组成。讨论了不同溶剂体系对其形貌的影响,得出在V_(DMF)∶V_(乙醇)=3∶1时.填充度为80%,Mn^(2+)与月桂酸硫脲咪唑啉季铵盐(SUDEI)的摩尔比为1∶3.5时分散性最好。A simple and convenient route has been successfully developed to prepare MnS hollow spheres with diameter of 300 nm under solvothermal conditions in DMF/ethanol solution at 160℃ for 12 h, in the presence of a special surfactant-quaternary ammonium salt of 2-undecyl-1- dithioureido-ethyl-imidazoline（SUDEI）. The products were characterized by TEM, SEM, IR, XRD and EDS, and the influence of different solvents on the MnS morphology is also discussed. It is found the optimum conditions for the synthesis of hollow MnS spheres are： VDMF： ∨ethanol=3： 1, filling degree 80%, and the mol ratio of Mn^2＋ to SUDEI 1：3.5.
