Abstract
The facilities of one-step preparation method of nickel nanoparticles by the interphase reduction of nickel oleate using sodium borohydride at room temperature without soluble polymer as a protective agent were studied. Nickel obtained by such technique was concentrated in aqueous phase as a black dispersion. The composition and morphology of the colloid's dispersive phase were investigated by transmission electron microscopy, XRD and IR-spectroscopy. The dispersive phase of the prepared colloidal solution represents crystalline spherical nickel nanoparticles with some admixture of nickel boride. Their average size varies between 2 and 6Â nm. In accordance with the IR-spectroscopy results the stability of the nickel colloidal dispersions was provided by the surfactant produced through the interphase reaction.
