Nickel sulfide (NiS) nanoparticles were synthesized by a simple electrochemical route. In this study, synthesis conditions of nickel sulfide nanoparticles were optimized by Taguchi robust design. The current application of the Taguchi method was successful in optimizing the experimental parameters of the electrochemical synthesis procedure of nickel sulfide nanoparticles. The effects of several main procedure factors (i.e., sulfide ion concentration, applied voltage, stirring rate and reactor temperature) on the particle size of synthesized nickel sulfide particles were investigated. The significance of these factors on the diameter of nickel sulfide particles was evaluated by the analysis of variance (ANOVA) and the optimum conditions for the preparation of nickel sulfide nanoparticles by the proposed electrochemical method was proposed. The prepared NiS nanoparticles at optimum conditions were characterized by various techniques i.e., SEM, TEM, XRD, EDX, FT-IR, UV–vis and PL.
