以醋酸镍和硫代乙酰胺为原料, 乙醇为溶剂, 在150 ℃的溶剂热条件下制备了硫化镍空心微球, 并用XRD, TEM, SAED和SEM对产物进行了表征. 结果显示, 这些空心微球由β-NiS和α-NiS组成, 从反应开始得到的α-NiS实心球通过内核的消溶演变而成.

NiS hollow microspheres were synthesized by the reaction of nickel acetate and thioacetamide in ethanol at 150 ℃. XRD, TEM, SAED (selected area electron diffraction), and SEM were utilized to characterize the products. The results show that the products were hollow microspheres made of β- and α-NiS, while the hollow spheres were transformed from the α-NiS solid ones.

Key words: nickel sulfide, hollow microsphere, solvothermal
