In snmmary, we list the main parameters of the chemical vapor deposition of carbon nanotubes the temperature of the growth, the carbon source, the materials and size of the catalyst, and the materials and surface properties of the substrate. 

SiCNWs can be fabricated by several methods for example, chemical vapor deposition (CVD), carbon nanotubes templates, laser ablation and thermal evaporation. Most of these methods need special apparatuses and complicated operation, and some of them need catalyst which reduces the purity and quality of SiCNWs. Thermal evaporation method is a low cost and un-complex way to fabricate SiCNWs using pre-oxidized silicon powder and methane gas as precursors without any metal catalyst. High yield of products are obtained per one synthesis. 

Recently, the efficacy of LDHs as catalyst precursors for the synthesis of carbon nanotubes via catalytic chemical vapor deposition of acetylene has been reported by Duan et al. [72]. Nanometer-sized cobalt particles were prepared by calcination and subsequent reduction of a single LDH precursor containing cobalt(II) and aluminum ions homogeneously dispersed at the atomic level. Multi-walled carbon nanotubes with uniform diameters were obtained. 

Low temperature chemical vapor deposition from ethanol was used for production of the samples. Selective deposition of carbon nanotubes took place under low temperature due to pyrolysis of ethanol vapor. Heating of substrate and pyrolysis of reagent vapor was done by a graphite heater, which was placed inside reactionary... 

Like in the preparation of single-walled carbon nanotubes, the chemical vapor deposition of MWNT consists in the generation of small carbon clusters or atoms from precursor compounds. The products precipitate in the shape of different carbon materials with the reaction conditions determining the specific stracture...

Multiwall carbon nanotubes (MWCNTs) have been synthesized by catalytic chemical vapor deposition (CCVD) of ethylene on several mesoporous aluminosilicates impregnated with iron. The aluminosilicates were synthesized by sol-gel method optimizing the Si/Al ratios from 6 to 80. The catalysts are characterized by nitrogen adsorption, X-ray diffraction, 27A1 NMR, thermogravimetric analysis (TGA) and infrared. The MWCNTs are characterized by TGA and transmission and scanning electron microscope.

The approaches used for preparation of inorganic nanomaterials can be divided into two broad categories solution-phase colloidal synthesis and gas-phase synthesis. Metal and semiconductor nanoparticles are usually synthesized via solution-phase colloidal techniques,4,913 whereas high-temperature gas-phase processes like chemical vapor deposition (CVD), pulsed laser deposition (PLD), and vapor transfer are widely used for synthesis of high-quality semiconductor nanowires and carbon nanotubes.6,7 Such division reflects only the current research bias, as promising routes to metallic nanoparticles are also available based on vapor condensation14 and colloidal syntheses of high-quality semiconductor nanowires.15...
