- Department of Mechanical Engineering, University of Tabriz, Tabriz (Iran, Islamic Republic of)
Highlights: ► Electrohydrodynamic atomization (EHDA) assisted chemical synthesis of nickel nanoparticles is reported. ► Substituting water with non-aqueous media prevents the formation of nickel hydroxide. ► Size of particles decreased from 10 to 20 nm down to 2–4 nm by using multi-jet mode. ► Synthesized nanoparticles have diffraction patterns similar to amorphous materials. -- Abstract: In this study nickel nanoparticles were prepared via chemical reduction of nickel acetate using sodium borohydride using electrohydrodynamic atomization (EHDA) technique. This technique was used to spray a finely dispersed aerosol of nickel precursor solution into the reductive bath. Obtained particles were characterized by means of X-ray diffraction (XRD), UV–Visible spectroscopy, and transmission electron microscopy (TEM). Results confirmed the formation of nickel nanoparticles and showed that applying EHDA technique to chemical reduction method results in producing smaller particles with narrower size distribution in comparison with conventional reductive precipitation method.
