Nickel Sulfide Nanoparticles

Nickel Sulfide Nanoparticles

Nickel Sulfide Nanoparticles as members of this family have received much attention due to their potential application as a transformation curing agent for materials used in various semiconductors, catalysts and cathodes of rechargeable lithium batteries. The nanoparticle can form as two crystalline structures depending on the temperature. The alpha form has a hexagonal phase (P63 / mmc) which forms at high temperatures, while the beta form has a rhombohedral cell unit (R3m) which forms at low temperatures. To date, different forms of Ni3S2 Nanoparticles, i.e. nanospheres, nanobars, nanoprisms, nano-needles, hollow spheres, flower-like architectures, curly-like nanocrystallines, layered laminate structures, etc. have been synthesized by various methods. These forms of nickel sulfide nanostructures could be obtained by hydrothermal, solvothermal, molecular and precipitation routes. However, the influence of nanoparticle morphologies on their physico-chemical behavior made interesting further efforts for the tunable synthesis of uniform nickel sulfide nanoparticles. Optimization is a fundamental step in the development of a nanomaterial synthesis procedure. The other advantage of fractional factorial design instead of sequential design is the ability to extract more information from the resulting experimental data. To the best of our knowledge, the synthesis of nickel sulfide submicron and nanostructures by various techniques has been previously reported in the literature. However, there is no report on the statistical optimization of the synthesis of nickel sulfide nanospheres by the chemical precipitation method without the use of a catalyst, surfactant or mold.
