Morphology and Phases of Ni-S Powders Synthesized by Chemical Route

摘要：

　　The nickel sulfides of NiS and NiS2 have been synthesized successfully at 180 ℃ and 160 ℃ by hydrothermal method from NiCl2·6H20,S powder and NaOH.The phases and morphology of the products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) respectively.Experimental results show that,the major phase of the powder product obtained at 180 ℃ is NiS2.The Ni-S powder obtained at 180 ℃ shows granular and hexagonal shapes with sizes of about 200~300 nm.The product powder obtained at 160 ℃ has the major phase NiS and minor phase NiS2.The morphology of this product was regular hexagonal flakes with side-length 200nm.
