Description The Ni, Au and Pt nanoparticles were prepared using (Ni(acac)2, HAuCl4 or H2PtCl6) precursors respectively. The precursor was dissolved in oleylamine and injected into preheated mixture of oleylamine and octadecene. The reaction mixture was cooled down to room temperature after time needed for nucleation and growth of nanoparticles. The nanoparticles were separated and purified. The metallic nanoparticles was stabilized in hexane and characterized. The alternative synthesis was reduction using NaBH4 in polar solvent. The precursors of gold or platinum were dissolved in water. The phase transferring agent was used for transfer of side products to organic solvent under intensive stirring. Organic phase was removed and NaBH4 was added. This mixture was stirring again to reduce PtIV into Pt0 or AuIV into Au0. Nanoparticles prepared by both methods were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM) in order to determinate average size, size distribution, stability and shape of the nanoparticles. Obtained results were discussed from the point of view of the size and stability.
