“…Previous studies about flame synthesis mainly focused on the fabrication of CNTs. It is recognized that the formation of CNTs using flame synthesis depends greatly on the catalytic metal (such as Ni-Cr, Ni-Cr-Fe, Co-SiO 2 ) [16,43]. The CNOs synthesized by diffusion flames were collected on a catalytic nickel grid [21].…”

“…To initiate the growth of nanotubes, two gases are bled into the reactor: a process gas (ammonia, nitrogen, hydrogen, etc) and a carbon-containing gas (such as acetylene, ethylene, etc.) [27][28][29][30] . Nanotubes grow at the sites of the metal catalyst; the carbon-containing gas is broken down at the surface of the catalyst particle, and the carbon is transported to the edges of the particle, where it forms the nanotubes.…”

Discovery of carbon nanotubes has great impact on the development of newer methodologies and devices useful for the analysis of various types of chemicals. The functionalisation of CNTs with biomolecules related to chemical and biological warfare agents makes these useful for the detection of these agents. The detection sensitivity can be increased manyfold. Various types of chemical and biological sensors were developed using various type of carbon nanotubes as well as nano particles of different metals.

“…A diffusion flame with a high angular velocity (i.e., low strain rate) produces more carbon sources due to the longer dwelling time compared to a flame with high strain rate and low angular velocity. In addition, they observed that the nickel-nitrate coated nickel substrate can provide better soot formation [50]. Oxygen plays a vital role in the formation of metal oxides to catalyze the tube formation; however, the excess oxygen may damage CNTs by oxidizing them.…”

In recent years, flame synthesis has absorbed a great deal of attention as a combustion method for the production of metal oxide nanoparticles, carbon nanotubes, and other related carbon nanostructures, over the existing conventional methods. Flame synthesis is an energyefficient, scalable, cost-effective, rapid and continuous process, where flame provides the necessary chemical species for the nucleation of carbon structures (feed stock or precursor) and the energy for the production of carbon nanostructures. The production yield can be optimized by altering various parameters such as fuel profile, equivalence ratio, catalyst chemistry and structure, burner configuration and residence time. In the present report, diffusion and premixed flame synthesis methods are reviewed to develop a better understanding of factors affecting the morphology, positioning, purity, uniformity and scalability for the development of carbon nanotubes along with their correlated carbonaceous derivative nanostructures.
