Nickel(IV) sulfide is a black solid with a lustre similar to copper. It is one of the four elements that are ferromagnetic and, because of this, finds numerous uses in magnetic materials such as permanent magnets. It is also a common component in stainless steel. The majority of nickel mined today comes from laterite and magmatic sulfide ores, which are called nickel ore. Nickel is one of the world’s most versatile metals and is used in many different industries, ranging from consumer electronics to catalysts for chemical production and energy storage.
Nickel sulfide is also an excellent material for the formation of nickel sulfide nanoparticles (NPs). NPs can be produced by two different approaches: the first method involves reaction of the nickel xanthate NiXa-C6 with oleylamine at room temperature. The other approach involves solvothermal conversion of the nickel xanthates at 200 degC with oleylamine as solvent and capping ligand.
Both methods yield a broad range of sizes of nickel sulfide NPs, ranging from 5 to 20 nm in diameter. TEM and bright-field TEM images of the NPs obtained via the solvothermal synthesis show that the NPs are well capped with oleylamine ligands. FTIR spectroscopy confirms the functionalization of the NPs with oleylamine, as characteristic vibrational bands corresponding to the amine group are observed.
