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

Abstract:

The nickel sulfides of NiS and NiS2 have been synthesized successfully at 180 °C and 160 °C by hydrothermal method from NiCl2•6H2O, 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 °C is NiS2. The Ni-S powder obtained at 180 °C shows granular and hexagonal shapes with sizes of about 200~300 nm. The product powder obtained at 160 °C has the major phase NiS and minor phase NiS2. The morphology of this product was regular hexagonal flakes with side-length 200nm.
