Synthesis Nickel Nanoparticles with Using Ultrasonic System and Characterization

In the past two decades, considerable attention has been devoted to the synthesis of metal Nanoparticles because of their unusual properties and potential applications in optical, electronic, catalytic, magnetic materials, and so on [1,2]. Solution reduction method is an easy technology for preparing Nanoscale particles in recent years. In this work, Nickel Nanoparticles with mean diameter (2.5-5) nm, was synthesized by the reduction of Nickel Nitrate with Hydrazine Hydrate in an aqueous solution by Poly vinyl pyrrolidone (PVP) as emulsifier and were sonicated for 45 minutes with using Ultrasonic radiation method and temperature of reaction was about 50 ◦C. An appropriate amount of NaOH, trace Acetone, and an elevated temperature were necessary for the formation of Nickel Nanoparticles
