“…Two different procedures were used for this work. In the first method, the conventional method [4,7,11], the catalyst was placed in the center of a quartz tube. The CVD furnace was heated to a desired temperature in the atmospheric pressure.…”

In this study, we describe the synthesis of carbon nanotubes (CNTs) by chemical vapor deposition at 500°C to 975°C, over Co 3 O 4 /MgO catalyst. The size of Co 3 O 4 nanoparticles is controlled by changing cobalt nitrate concentration in aqueous solution by impregnation method. The main object of this study is the synthesis of CNTs that started suddenly without any preheating of catalyst nanoparticles. The effect of sudden initiation and conventional preheating processes of catalyst nanoparticles on yield of CNTs was then described. The results suggest that this sudden initiation of synthesis process affects the carbon yield and morphology of CNTs.

“…Recently, scientific groups dealt with the mechanism of the formation of carbon nanotubes. The role of pretreatment [4,5] and the size of catalyst nanoparticles have been particularly discussed [6,7]. The study shows that the yield of CNT preparation significantly depends on metal particles on supported catalysts.…”

“…To date, several approaches to CNT and CNT composite synthesis using a spray pyrolysis method have been developed [10][11][12][13][14]. Spray pyrolysis has the following advantages making it well suited for production of CNTs and their composites: it is versatile and economical; it yields a high-purity product and it uses a continuous process and simple design [10,12,15].…”

“…Spray pyrolysis has the following advantages making it well suited for production of CNTs and their composites: it is versatile and economical; it yields a high-purity product and it uses a continuous process and simple design [10,12,15]. In addition, the size of primary nanoparticles was maintained or slightly increased, although they were exposed to high temperature [16,17].…”

“…In turn, the chirality is determined by the CNT diameter and the orientation of the rolled graphene sheet with respect to the CNT axis. Hence, control of the catalyst size is an important step towards the properties of CNTs, and various studies on the preparation of size-controlled transition metal catalyst particles for CNT growth have been carried out [13][14][15].…”
