Superfine paramagnetic nickel particles were synthesized by using different anionic and cation surfactants in the presence of propylene glycol. Surfactants including gum arabic, gelatin, PVP and tri-sodium citrate were used. SEM analysis proved that the morphology of nickel particles was perfectly spherical with little agglomeration. The morphology of microspheres was changed with variation of anionic and cationic surfactants, but majorly the spherical shape of nickel particles was retained. The purity of superfine nickel particles was also confirmed with EDS results which confirmed the presence of superfine nickel particles. The XRD analysis results also indicated the presence of "fcc" crystal in the superfine particles. The magnetic field analysis designated the existence of magnetic properties in synthesized superfine nickel particles. Surface area properties were also measured with the help of BET analysis which determined the enhanced catalytic property of these particles. Overall the synthesized nickel superfine microspheres possesses improved morphology and magnetic properties with the addition of PVP as surfactant as compared to gum arabic, gelatin, and tri-sodium citrate.
