“…This result is supported by a previous study by Lee et al [7] who synthesized long length and high density VA-CNTs by CCVD on Al supported Fe catalyst. They had validated that Fe results in best crystallinity CNTs [8]. In addition, Fe has a high value of surface diffusivity.…”

“…On the other hand, the effect of water vapor towards flame distribution and the growth region of CNT is also studied prior to developing a baseline model. Based on literature review, waterassisted CNT synthesis was solely studied using CVD method [8]. Owing to that, the water content applied in the CVD, 100 sccm equivalent to 0.7% water vapor serves as a reference in establishing the baseline model.…”

Research on carbon nanotubes (CNTs) has been performed extensively. On top of that, water-assisted synthesis of CNT has started to emerge with captivating effect towards growth of CNT. The present study investigates a baseline inlet condition for water assisted case utilizing diffusion flame that imitates the temperature distribution and growth region of CNT without water vapor, on the basis of experimental data of non-water assisted high yield CNTs. To affirm the effect of water vapor, 35% to 70% of water vapor has been added replacing the fuel side nitrogen content. The results prove that water vapor suppresses the flame where the maximum temperature drops with increasing concentration. Consequently, this affects the length and growth region of CNTs. The region width has been reduced for about 7.4% to 18.5% with water vapor. This shows that excessive water poorly affects the growth of CNTs. On the other hand, the region has also shifted for about 0.64 mm to the fuel side (5.7%) from the origin when 70% of water vapor was added. Following this, the impact of catalyst towards CNT growth is subsequently presented whereby a comparison is made between Fe and Co to synthesize CNT using flame synthesis. Based on the result, Fe possess better activation for the CNTs to grow as compared to Co. A significant difference between the predicted CNT length for Fe (147 μm) and Co (56 μm) is attributed to their diffusivity values.

“…The concept was later reproduced by others [127][128][129][130]. In one of these works, two types of catalytic systems based on Fe or Co were compared [128]. The material produced on the surface of the former metal was slightly purer, but both CNT fractions showed, in fact, a high level of adulteration.…”

This review summarizes the up-to-date techniques devised to synthesize carbon nanotubes (CNTs) from liquid or solid precursors of sustainable nature. The possibility to replace petroleum-based feeds for renewable resources such as essential oils or plant shoots is critically examined. The analysis shows that the complex nature of such resources requires the optimization of the reaction conditions to obtain products of desired microstructure and chemical composition. However, appropriate tuning of the process parameters enables the synthesis of even high-purity single-walled CNTs with a spectrum of demonstrated high-performance applications at low cost. The sheer number of successful studies completed on this front so far and described herein validate that the development of techniques for the manufacture of such products of high-added value from common precursors is not only possible but, most importantly, promising.

“…Increasing the deposition temperature caused the formation of well aliened straight nanotube bundles with high crystallinity as well as a higher carbon content; 900 °C being the optimal temperature. Suriania et al . explored the research on the effect of Fe and Co metallic catalysts on the growth mechanism of carbon nanotubes, while using Palm oil as a carbon source.…”

A recent development in the manufacturing of carbon nanotubes is the usage of renewable feedstocks as a carbon source. This new development is receiving much support and is a source of excitement among the global research communities due to the positive environmental impacts, reduced carbon footprints, and economic benefits. Various types of renewable feedstocks such as vegetable oils, plant derivatives, and other types of biomasses have been used for the green synthesis of carbon nanotubes by employing conventional fabrication techniques. As the global demand increases for green manufacturing, efforts to synthesize carbon nanotubes from renewable resources are receiving immense attention while also strengthening the concept of biorefinery. This also enables the efficient use of resources as well as improved waste management. The present review summarizes the recent developments and current status of the synthesis of carbon nanotubes using renewable feedstocks along with technical discussions, opportunities for novel precursors, and future directions.
