摘要

Synthesis of nickel nano-particles with a coating of a hydrophilic surfactant has been carried out by use of sodium borohydride and sodium formaldehyde sulfoxylate (SFS) in aqueous medium. It is observed that an ideal temperature range for formation of nickel nanoparticles is between 50 and 100 ℃. Phase-pure nano-nickel can be obtained by use of SFS. X-ray diffraction measurements (XRD) revealed broad pattern for fcc crystal structure of nickel metal with particle diameter of about 10-15 nm. Scanning Electron Microscopy (SEM) showed that there is clustering of spherical particles in dry state and Transmission Electron Microscopy (TEM) gave a particle size of about less than 10 nm.
