Yoon et al. (2004) Catalytically grown carbon nanofibers (CNF) were activated with KOH. The structural changes of CNFs were investigated using SEM, transmission electron microscopy (TEM) and XRD. The observed increase in surface area in KOH activation of CNF is ascribed to local broadening of graphene interstices or local bum-off of graphene layers. Activation under severe conditions destroyed the fiber structure of CNF. Activated CNFs were applied as an electrode for electrical double layer capacitors to be compared to active carbon fibers in terms of the surface properties.

An article by lijima showed that carbon nanotubes are formed during arc-discharge synthesis of C, and other fullerenes also triggered an outburst of the interest in carbon nanofibers and nanotubes. These nanotubes may be even single walled whereas, low-temperature, catalytically grown... 

An innovative way to get a high surface area and at the same time allow free access of the reactant to the catalytic sites is the use of nanofibers grown on the outer surface of the structured catalyst Carbon nanofibers grown in the cavities of open cell foam can be regarded as the inverse of a porous particle [41, 42] (Figure 11.17). 

Carbon nanofibers with controllable nanoporous structures can be prepared via different ways. An oldest method is the catalytic decomposition of certain hydrocarbons on small metal particles such as iron, cobalt, nickel, and some of their alloys [80]. The mechanism includes hydrocarbon adsorption on a metal surface, conversion of the adsorbed hydrocarbon to adsorbed surface carbon via surface reactions, subsequent segregation of surface carbon into the layers near the surface, diffusion of carbon through metal particles, and then precipitation on the rare side of the particle [81]. The size of the catalyst nanoparticles seems to be the determining factor for the diameter of the carbon nanostructures grown on it. Small nanoparticles catalyze this grown better than the big ones due to that exhibit pecu-...
