A Novel Synthesis Process for Making Nickel Oxide Nanoparticles

Abstract

The main aim of this research was to prepare nanoparticles of nickel oxide through a new mixed reverse microemulsion route. Quaternary microemulsion (water/surfactant/co surfactant/oil-phase) was used to synthesize nickel oxide nanoparticles. The microemulsion was prepared by Tween-80, Aerosol-OT, n-Propanol, Cyclohexane, and Nickel Chloride. Previously nickel oxide nanoparticles were synthesized by reverse microemulsion method but the novelty of the process lies in the fact that conventionally either cationic or anionic or non ionic surfactants are used for the synthesis of nickel oxide nanoparticles.Whereas in the present developed novel process preparation of nickel oxide nanoparticleshas been carried out using a unique blend system consisting of Tween -80 and AOT. The average particle size of as synthesized nickel oxide powder, calculated by Scherrer equation, is observed to be 14 nm. The X -ray diffraction pattern confirms the p resence of pure bunsenite phase withFCC Scanning Electron Microscopy (SEM) shows that particles have spherical morphology.
