Synthesis of Flower-Like and Coil-Like Cobalt Nanopartilce in Aqueous Media, Its Characterization and Application: Controling Shapes of Nano Cobalt with Synthesis Methods

we demonstrated two different methods to synthesis cobalt nanoparticle and characterization obtainednanoparticle using SEM, TEM, XRD, TGA and VSM. The formation of nanoparticle with different shape andmorphology depends to using methods; Analysis and comparison of characterized results have indicated it. Thesenanoparticles can be used as catalyst in organic synthesis such as Heck cross-coupling reaction.
