Nickel nano particles (NNPs) can be synthesized by physical, chemical, biological methods. The reduc-tion of nickel nitrate salt to pure nickel nanoparticles using naturally occurringAzadirachta indica(neem) leaves extract as a reducing agent.In this work qualitative and economical NNPs are synthesized by using Green method. In aqueous solution of Nickel nitrate (1M) Azadirachta indicaleaves extract is slowly added and ultra sonicated for 1Hr at 80°C. The solution is then directly heated and dried to get Nickel oxide powder. As obtained nickel oxide was then reduced to NNPs at different range temperature (700-900°C) in hydrogen atmosphere. The effect of varying temperature for getting different quality and quantity of NNPs were studied. These NNPs was then characterized by (XRD) X-ray diffraction, SEM (Scanning Electron Microscope) and FTIR (Fourier Transform Infra-Red Spectros-copy). It was found that the quality and quantity of NNPs varies with different experimental conditions.
