DescriptionCarbon nanotubes have been extensively studied for two decades. CNTs attracted scientists' attention due to their exceptional mechanical, chemical, and electrical properties. Multiple methods including arc discharge, laser ablation, CVD, and several flame synthesis methods are used to grow CNTs. The most significant problem with all current methods is the high cost and low yield of the generated materials. Furthermore, none of the current mechanisms explain completely the formation mechanism of CNTs.
This study utilizes methane-based premixed flames to grow CNTs in a one-dimensional, stagnation point geometry. Vaporized ferrocene Fe(C5H5)2 is seeded into the flame and acts as a catalyst for nanotube growth. CNTs are collected from the substrate located 1.5 cm away from the burner nozzle and are analyzed using TEM, SEM with EDS, and Raman spectroscopy to ascertain the presence of nanotubes.
Different carbon structures including carbon nanofibers, MWNTs, and SWNTs are generated using this technique. The presence of MWNTs is observed under TEM, while nanofibers are viewed under SEM. Raman spectroscopy is used to identify SWNTs.
