Synthesis of Carbon Nanotubes by CVD over Fe Catalyst Prepared in Spin Coating on SiO2/p-Si(100)

Full Text PDF


Carbon nanotubes (CNTs) have been grown by the decomposition of C2H2 over thin catalyst film in order to investigate the growth mechanism of CNTs by chemical vapor deposition (CVD).The catalyst was prepared from an iron chloride FeCl3 precursor solution that was spin –coated on SiO2 substrate. The growth mechanism and the length and the diameter of the CNTs were greatly influenced by the precursor concentration, the time deposition and the temperature and the ratio of C2H2:N2 are fixed. Transmittance electron microscopy and Scanning electron microscopy and Raman spectroscopy and X-ray diffraction have been carried out in order to investigate the behavior of the growth process. The iron chloride film contact with the C2H2:N2 reaction atmosphere.
