Abstract: Carbon Nanotube (CNT) is a new form of carbon, have aroused huge interest in the research community because of their interesting electronic structure. The CNTs are possibly handy in an extensive variety of solicitations. They unveil phenomenal asset, strange electrical properties and efficient heat conductors. Currently Chemical Vapour Deposition (CVD) has been widely used for the preparing carbon nanotubes because of its simplicity, high throughput and low running cost. It is also easy to control the growth parameters compared to other methods. In the present work methane is used as the source of carbon and ferric nitrate is used as a catalyst. Also, zeolites are used as absorbents and support for catalysts. The growth is carried out in a tubular furnace. The surface morphology, vibrational and structural properties were studied by using FESEM, laser Raman. FESEM micrograph shows the growth of carbon nanotube with different shapes. The length of the tube is ~1.08µm while its diameter is ~70nm. Raman spectra shows the absence of radial breathing mode (RBM) at lower Raman shift and the D and G- band evidence the presence of multi walled carbon nanotubes. XRD pattern reveals that, the intensity of graphite peaks are very subdued because the presence of higher content of zeolite.TGA curve shows, the as grown CNT has a weight gain due to oxidation or oxygen pickup by zeolite. Carbon nanotubes is an advance developing field in research. Carbon nanotubes are the strongest and stiffest materials in terms of tensile strength and elastic modulus. The present work focuses on the growth of Carbon nanotubes using chemical vapour deposition. Although there are many methods, the chemical vapour deposition is chosen because of its simplicity, high throughput and low running cost. Also it is very easy to control the growth parameters compared to other methods. . Carbon nanotubes has a wide application range in the field of Gas sensors, medical science for drug delivery system, field emission, energy storage and solar cells.
