“…As a result, they proposed that temperature is a dominating factor for CNT diameter control. The same conclusions have been also reported by other researchers [9,10,25,[69][70][71]. The main effects of increasing the reaction temperature are to increase the metal particle size during the CVD growth of CNTs, and consequently the nanotube diameter.…”

“…Materials with capability of decomposing hydrocarbon and CNTs formation are employed as catalyst in CCVD processes. However, it has been found that only the hydrocarbon molecules' decomposing ability of catalyst could not be accounted for CNT formation [9,[12][13][14]. These results emphasize that careful selection of the catalyst is a dominating factor in CCVD synthesis of CNTs.…”

“…The effectiveness of the method mostly depends on the surface properties of the support through interaction with the active metal phases [9,20,21,23,42]. The sol-gel synthesis method has been reported to ensure a highly homogeneous distribution of transition metal in the matrix on which the aligned nanotubes grow [44][45][46][47].…”

“…There is an optimal metal content ratio between catalyst and support, which leads to the CNTs synthesis with the desired properties at maximum yield. Increasing the metal percentage is fruitful only if it enhances the available active sites for CNT growth, instead of increasing the mean particle size of the metal [9,19,21,25,30]. At first, by increasing catalyst metal amount on support, carbon deposition rate and yield is ramped up since more active catalytic sites are available for carbon deposition.…”

“…However, CCVD has been widely applied, as it offers a promising route for bulk production of CNTs, which can lead to commercialization [3,[5][6][7]. The attraction and development of CCVD for growing CNTs by the scientific community can be attributed to the following facts: lower reaction temperature so lower cost, high purity, possible aligned carbon nanotubes production, relatively high yield of products, and the good potential for large-scale production [6][7][8][9][10]. Considerable efforts have been made to study the key parameters on CNTs productivity and morphology in CCVD process.…”

a b s t r a c tCarbon nanotubes (CNTs) are pure carbon in nanostructures with unique physico-chemical properties. They have brought significant breakthroughs in different fields such as materials, electronic devices, energy storage, separation, sensors, etc. If the CNTs are ever to fulfill their promise as an engineering material, commercial production will be required. Catalytic chemical vapor deposition (CCVD) technique coupled with a suitable reactor is considered as a scalable and relatively low-cost process enabling to produce high yield CNTs. Recent advances on CCVD of CNTs have shown that fluidized-bed reactors have a great potential for commercial production of this valuable material. However, the dominating process parameters which impact upon the CNT nucleation and growth need to be understood to control product morphology, optimize process productivity and scale up the process. This paper discusses a general overview of the key parameters in the CVD formation of CNT. The focus will be then shifted to the fluidized bed reactors as an alternative for commercial production of CNTs.

Preliminary results of Raman spectroscopy are presented on “in situ” growth of carbon nanotubes in a CVD‐cell which is optionally coupled to a mass spectrometer (MS). The system allows to analyze the differences in the content of the types of carbon nanotubes in the sample during the processes after 2 min, 5 min, 10 min, 15 min, 20 min and 30 min. The evolved gases in the throughout synthesis were analyzed in the MS mode. Two kinds of experiments were performed: in argon atmosphere at atmospheric pressure and under vacuum at low pressure, both with CH4 as a carbon feedstock. The temperature of the experiments was set up to 600 °C. The detailed study of the process can lead to a better understanding of the carbon nanotube growth mechanism. The analysis of these phenomena is supported by high resolution transmission electron microscopy (HR‐TEM). In addition, thermogravimetric analyses of the finally obtained products in the two experiments are presented. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
