Fourier transform infra-red (FTIR) properties of carbon nano tubes prepared from camphor oil by thermal chemical vapor deposition / Siti Nazirah Abu Bakar

Effective and economical methods to produce carbon nanotubes are necessary for future technology as well as the development of nano-size devices. Limited progress has been reported in producing carbon nanotubes. In this study, carbon nanotubes have been produced using Thermal Chemical Vapor Deposition (TCVD) method from camphor oil, C10H16O. Catalyst which nickel (II) nitrate hexahydrate, Ni (N03)2.6H20 was dispersed onto silicon substrate using spin coater. The silicon substrate was heated at high temperature and the camphor oil was vaporized in duo-furnaces CVD. The effect of different deposition* temperature onto carbon nanotubes grown was investigated. Fourier Transform Infra-Red (FTIR) spectra were recorded to characterize the chemical properties. The grown carbon nanotubes also characterized using Field Emission Scanning Electron Microscope (FESEM) to observe the structure and uniformity. The FTIR, spectra show the deposition temperature affect the quantity of carbon nanotubes grown interpreted from the intensity of peak and from this research, the optimum temperature to produce the CNTs is 700°C. This was confirmed by FESEM images. The images also show the majority of carbon nanotubes produced has smooth surface.
