Abstract

Carbon nanotubes (CNT) have widespread potential usage in applications related to optical, thermal, mechanical, electrical and electronics engineering. Pyrolysis method is a very well known process for synthesizing CNT. This report discusses about the single zone pyrolysis technique to synthesize the mixture of single and multi - walled carbon nanotubes. CNTs were synthesized by single zone pyrolysis method at 1000 ̊C temperature. A parametric study of the carbon nanotube growth has been conducted by optimizing various parameters such as volume of benzene and concentration of catalyst precursor ferrocene. Morphological and chemical analyses were carried out by using field emission scanning electron microscope (FESEM) and micro-Raman spectroscopy technique, respectively. FESEM data reveals the presence of single and multi - walled carbon nanotubes with diameters in the range of 14 - 69 nm. Raman spectra show the D, G and 2D peaks, which confirm the presence of CNT and radial breathing mode confirms the presence of single wall nanotube.
