Figure 2.31 Schematic representation of the formation of Co/MWNT powders: (a) Dispersion of MWNTs in dioctyl ether and oleylamine; (b) heterogeneous nucleation of Co nuclei on MWNTs (c) growth and coalescence of Co nuclei to form composite powders; (d) and 2.8 Transition Metal-Based Nanocompositesj79 (e) SEM micrographs of composite powders showing formation of pearl-necklace like structure.

Figure 2.32 (a)–(d) show SEM micrographs of the Fe/MWNT nanocomposite. The micrographs reveal dense growth of MWNTs in the matrix and within cavities of the composite. This is because iron also serves as an excellent catalyst for nanotube growth. The CNTs form bridges across the cavities in the iron matrix.
