Abstract

By the liquid-reduction process, the nanometer spherical cobalt powders with fcc structure and a crystal size of 10 nm, are prepared using the regents of cobaltous salt as precursor and 1,2-propanediol as reducing agent. XRD, TEM are applied to characterize the phase and morphology of the as-prepared products. Both the reaction process and mechanism of the polyol reduction process are discussed preliminary through FT-IR spectra of the systems before and after reduction.
