Synthesis of Nickel Nanoparticles from Nickel Hydrazine Complex Solution Using Ultrasonication

The influence of ultrasonication was investigated on the synthesis of nickel particles from aqueous solution including nickel hydrazine complex. Nickel nanoparticles were formed by heating up precursor solution having been prepared under ultrasonication in advance. The mean size of nickel nanoparticles decreased with increasing time of ultrasonication, and it reached 43 nm with ultrasonication for 60 min.
