“…The use of graphite as a support is particularly interesting despite leading to the formation of disordered carbon nanostructures, in agreement with studies by Yacamán et al 25 The ease with which one can cleave relatively few graphitic layers affords facile sample preparations for TEM studies. This is seen in Figure 5, in which a bamboo-like carbon nanotube is imaged at various magnifications.…”

Using thermal CVD, the synthesis of multi-walled carbon nanotubes exhibiting roots anchored directly onto ␣-alumina supports, rather than the catalyst particle, is reported. At such roots, the alignment of the graphitic planes with the support lattice fringes depends on the support crystal structure and orientation.Surface defects may alter the reactivity of the surface or control the anchoring of supported atoms or nanoparticles.We argue this surface defect is provided by the catalyst particle's edge interaction with the support, in other words its circumference. The development of oxide-based catalysts is attractive in that they potentially provide an appropriate solution to directly integrate the synthesis of carbon nanotubes and graphene into silicon-based technology.

“…The minimal tube diameter that can be so achieved is that of the catalytic particle. Several authors [12][13][14][15][16][17] tried to adjust parameters such as the catalyst composition and the reaction atmosphere to maximize the nanotube yield and to minimize the tube diameter. Ivanov et al 16 have reported very small amounts of thin tubes (4 nm), and tubes up to 60 mm long, but they point out that the longest tubes are also the thickest.…”

Carbon nanotubes can be produced by the catalytic decomposition of hydrocarbons on small metal particles. However, nanotubes are generally produced together with non-tubular filaments and tubes coated by pyrolytic carbon. We propose a novel catalyst method for the in situ production, in a composite powder, of a huge amount of single- and multiwalled carbon nanotubes, having a diameter between 1.5 and 15 nm and arranged in bundles up to 100 μm long. We anticipate that dense materials prepared from such composite powders could have interesting mechanical and physical properties.

“…Even though many synthetic methods are known for carbon materials, most of them still require harsh and rather expensive processing conditions such as very high temperatures, arc discharge, or decomposition from the plasma or gas phase [4][5] [6].…”
