“…This shows that the formation of carbon fibres on SiO 2 particles. In addition, a very weak diffraction peak corresponding to Fe 3 C can be formed at 2 θ = 43° as a result of carbon atoms dissolution in iron during carbon fibre growth [17, 18]. To imply further the formation of carbon fibres, the sample was treated by HF to get rid of SiO 2 .…”

Carbon microfibres (CMFs) were synthesised on SiO 2 particles by catalytic chemical vapour deposition at 1200°C using ethanol as carbon precursor, iron nitrate as the catalyst precursor, and nitrogen as a carrier gas. The structure and morphology of the products were characterised by X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy and Raman spectroscopy. CMFs obtained after a deposition time of 5 h have a diameter of 5-10 μm and a length of a few hundred micrometres. In the deposition process, Fe-Si-O-C droplets were first formed on the surface of SiO 2 particles, and then carbon fibres grew as a result of the catalysis of the droplets. Carbon fibres have the higher graphitic structures when the deposition process is conducted at 1200°C.

“…Carbon nanotubes (CNTs) have become the subject of intense investigation since 1991 because of their marvelous electrical, mechanical, electromechanical and chemical properties [1][2][3][4][5][6][7][8][9][10][11][12]. There are two different types of CNTs: single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs).…”

The effect of chemical solutions on the dispersion of single-walled carbon nantubes (SWCNTs) was studied. The SWCNTs were dispersed using several chemical solutions such as isopropyl alcohol (IPA), dichloromethane (DCM), acetone and triton X-100 (Triton-X) under ultrasonically process. The results show that the types of chemical solutions greatly affect the dispersion of SWCNTs. The IPA solution is found to be the best solution to disperse SWCNTs using ultrasonication process due to the difficultly of evaporation in room temperature to get a transparent solution.

“…Most of the papers available in the literature about growth of CNTs on iron based catalysts report growth of SWCNTs [3][4][5][6][7][8][9][10][11][12]. However, most of the reported results obtained with cobalt-based catalysts concern formation of MWCNTs [13].…”

Magnetite (Fe3O4) nanoparticles were synthesized in aqueous solutions without any surfactants. The Fe3O4 nanoparticles are nearly spherical and have an average diameter of 10.33nm and a narrow size distribution. Bundles of single-walled carbon nanotube (SWCNT) were synthesized using these Fe3O4 nanoparticles supported by MgO. Transmission electron microscopy (TEM) images show that tremendous amount of bundles SWCNT with uniform diameters were produced. The average diameter of bundles SWCNT is 1.22nm. Raman spectrum shows that well graphitized SWCNTs were formed based on the low ratio of ID/IG. Fe3O4 nanoparticles could be an effective active metal to synthesize large quantity bundles of SWCNT.
