Abstract
Cobalt, nickel, copper, and tin nanosized particles were synthesized through a borohydride reduction method with a reducing agent of NaBH4. The reductive precipitation was carried out at room temperature and atmospheric pressure. The nanoparticle powders were synthesized from water solutions of sulfate salts. The obtained nanosized particles were investigated by scanning electron microscopy (SEM) and XRD analyses. The SEM micrographs showed the nanoparticles’ morphology and structure. The chemical elements’ distribution was determined by energy dispersive spectroscopy (EDS) analysis. The X-ray diffraction (XRD) analysis determined the phase composition and state (amorphous or crystalline).
