Synthesis of Carbon Encapsulated Mono- and Multi-Iron Nanoparticles

Figure 1

(a) SEM image shows agglomeration of CEINPs produced under nitrogen. (b), (c), (d), (e), and (f) TEM images of CEINPs and CEMINPs are shown from N0, N25, N50, N75, and N100 samples, respectively. It is evident that the morphologies of carbon and iron were changed by increasing nitrogen ratio over helium. The increasing trend in carbon shell formation and the decreasing trend in iron formation are remarkable. Merge and formation of iron nanoparticles from N100 to N0 revealed the role and effect of coalescence in formation of CEINPs and CEMINPs.
