Raman spectra of nickel(II) sulfide

Polyol synthesis of α-NiS particles and its physico-chemical properties

“…It is well known that NiS has dimorphs like α-NiS hexagonal phase, which is stable at high temperature while β-NiS has rhombohedral phase, which is stable at low temperature. The phase transitions mainly occurred while altering the composition and temperature change in between 282 and 379 1C [8,9].…”

“…The literature depicts that NiS nanoparticles with different nanostructures have been prepared by different wet chemical methods including hydrothermal treatment [7,[10][11][12][13], ion exchange [14], solid state [15], solvothermal route [8,[16][17][18], micro-emulsion [19], microwave [20], hydrothermal via microwave [21], polyamine assisted solution-phase [22], sonochemical [23], polyol [24], solution phase [25], thermal sulfuration [26], thermal decomposition [27], and studied their detailed structural [28], morphological [9][10][11][12][13][14][15][16][17][18][19][20][21][22], optical [8,10,25], magnetic [13][14][15][16], catalytic [16,28], and electrochemical properties [11][12]16,…”

Synthesis of NiS nanoparticles using a sugar-ester nonionic water-in-oil microemulsion

“…Among these nanomaterials, nickel sulfide nanoparticles have become subject of intense investigations recently due to its potential application in various fields such as IR detectors, solar storage devices, photoconductive materials and hydrodesulfurization catalysis [3,4]. The electromagnetic property of the nickel sulfide (NiS) is interesting as it transforms from a paramagnetic metal to an antiferromagnetic semiconductor upon cooling under the transition temperature, T t f 379 jC [5].…”
