56. Effect of Sensitization on Electroless Nickel Plating of MoS₂ Nanoparticles

In this work, the effect of the sensitization process on the electroless nickel coating over the MoS₂ particle surface was studied. The surface of the MoS₂ particles was coated with nickel (Ni) using the electroless plating method because it is relatively efficient and cost effective. Two samples were synthesized; while one of them was sensitized using SN, the other was not sensitized and both samples were annealed after the plating process. The XRD pattern of the surface of both samples showed the presence of Ni in fcc structural phase along with MoS₂ phase. The surface morphology of all the samples was observed using FESEM and it is observed that the treatment with SN forms a uniform coating over the MoS₂ particles along with rod-like structures whereas the non-sensitized sample shows irregular coating of Ni over MoS₂ particles without rod-like structures.
