Mechanochemical Preparation of Cobalt Nanoparticles through a Novel Intramolecular Reaction in Cobalt(II) Complexes

Figure 4

SEM show morphologies and particle size distributions in metallic cobalt nanoparticles (Co1 and Co2) aggregated nanosheet with thickness 35–60 nm; (Co3 and Co4) aggregated spherical particles with size 50–80 nm; (Co5 and Co6) aggregated nanosheet with thickness 25–35 nm.
