Parametric study of atmospheric-pressure single-walled carbon nanotubes growth by ferrocene–ethanol mist CVD

The use of organometallic transition metal complexes in the synthesis of shaped carbon nanomaterials

“…Chaisitsak et al observed that the diameter of SWCNTs that were produced when T > 650°C increased with temperature [54]. This was confirmed by the appearance of narrow radial breathing mode (RBM) peaks in the Raman spectra (ca 200 cm À1 ) of the SWCNTs.…”

“…Addition of ethanol to FcH has been shown to give SWCNTs at lower temperature than that found for hydrocarbon reagents [54]. This could be due to the lower decomposition temperature of ferrocene in ethanol [55] and/or the etching effect of OH radicals generated from the ethanol precursor [56].…”

Present Advancement in Production of Carbon Nanotubes and Their Derivatives from Industrial Waste with Promising Applications

“…If a feasible process could be developed for transforming those available carbon-rich wastes into high value-added products like CNTs, economic benefits could be made through simultaneously solving the plastic wastes and CNT production shortcomings. It seems that the amount of published studies attempting to synthesize CNTs from such industrial wastes were scattered and limited because most of them were exclusive projects or (Bai et al, 2003;Lee et al, 2003;Chaisitsak et al, 2007;Zhang et al, 2008;Gong et al, 2014;Bajad et al, 2015). Furthermore, regarding to a common issue on using specific reactor system which would be promising for scalable production, some typical reports available in the public domain could be summarized in Table 2.…”

“…2. Feedstock would be introduced into the reactor by many means, such as spraying nozzle, ultrasonic nebulizer or even static container (Vilatela et al, 2015;Chaisitsak et al, 2007;Charinpanitkul et al, 2009b). Some inert carrier gas would be supplied into the reactor for carrying the hydrocarbon precursor which would be vaporized by regulated heating with a designated ramp rate for ensuring the steady flow of carbon sources into the reaction zone.…”

Carbon nanostructures with different dimensionality – From synthesis to applications

“…This simplicity also holds great possibilities for a wide range of variation, as it is clearly demonstrated by the sheer number of CVD procedures found in literature. Some of the most notable types besides the "simple" CVD are the microwave plasma-enhanced CVD [91], filament assisted CVD [92], water assisted [93] CVD, alcohol CVD [94], etc. There are some common parameters though, that remain fairly constant in all CVD types, like the gases used for producing inert atmosphere.…”
