“…It is believed that most of these catalyst particles present at the tips are lost during acid (HCl) treatment. Moreover, it is also believed that catalyst particles are detached from the tips of the CNTs during sonication for the sample preparation of the TEM measurement because they are loosely bound [25]. This may be another reason, why catalyst particles are not seen in TEM image of acid treated CNTs.…”

“…This technique is even simpler than the technique employed by Terrones et al, Rao et al, and Lee et al [11,14,15]. The detailed experimental procedure of the single-stage furnace pyrolysis set-up has been discussed elsewhere [25,26]. In brief, to synthesize various CNs in the present technique, a mixture of 18 mg of catalyst source material ferrocene and 2 ml of carbon source material tetrahydrofuran (THF) is taken in a reaction quartz tube of diameter 1.0 cm and length 70 cm, closed at one end.…”

“…However, in the TEM images, the catalyst particles are not found at the tips of normal as well as CCNTs. Probably, the catalyst particles are detached during acid treatment and sonication process, since they are loosely bound [25].…”

Tin oxide nanoparticles are synthesized using solution combustion technique and tin oxide – carbon composite thick films are fabricated with amorphous carbon as well as carbon nanotubes (CNTs). The x-ray diffraction, Raman spectroscopy and porosity measurements show that the as-synthesized nanoparticles are having rutile phase with average crystallite size ∼7 nm and ∼95 m2/g surface area. The difference between morphologies of the carbon doped and CNT doped SnO2 thick films, are characterized using scanning electron microscopy and transmission electron microscopy. The adsorption-desorption kinetics and transient response curves are analyzed using Langmuir isotherm curve fittings and modeled using power law of semiconductor gas sensors.

“…Various methods have been developed for the synthesis of carbon nanotubes, including metal catalyzed chemical vapor deposition (CVD), 9,10 arc evaporation, 11 laser ablation of carbon, 12,13 catalytic decomposition 14 and pyrolysis. 15,16 Some of these techniques can produce nanotubes in sizable quantities. However, need of high temperature and reaction time make their manufacturing costs high and still prohibit widespread commercialization.…”

Synthesis of Carbon Nanotube bundles has been achieved by simple and economical solvothermal procedure at very low temperature of 180 °C. The product yield obtained was about 70-75%. The optimization of reaction conditions for an efficient synthesis of CNTs has been presented. The CNTs are obtained by reduction of hexachlorobenzene in the presence of Na/Ni in cyclohexane. The X-ray diffraction, Fourier transform infrared and Raman spectral studies have inferred us the graphene structure of the products. The CNTs formed as the bundles were viewed on scanning electron microscope, transmission electron microscope and high-resolution transmission electron microscope. These are the multiwalled CNTs with outer diameter of 5-10 nm, the inner diameter 2-4 nm and cross sectional diameter up to 5 nm. Brunauer-Emmett-Teller (BET) based N 2 gas adsorption studies have been made to obtain BET surface area and H 2 storage capacity. Effect of the experimental variables such as reaction temperature, amount of catalyst and the amount of carbon source were investigated. It is found that they affect significantly on the product nature and yield.
