Abstract. The knowledge of fabrication method plays an important role in the preparation of aligned carbon nanotubes (ACNT) from natural hydrocarbon feedstock. Here ACNT were successfully synthesized by two-stage catalytic chemical vapor deposition method using organic oil (camphor oil) as a precursor. Synthesis was carried out at a fixed growth temperature of 800 o C and in different growth time: 10, 20, 30, 40, 50 and 60 minutes. The optimized condition for the growth of ACNT produced a small amount of by-product amorphous carbon and highly uniform crystal structure. The experimental results demonstrated that formation ACNT is also dependent on the growth time. The nanotubes were characterized by field emission scanning electron microscopy and micro-Raman spectroscopy. Thermal properties were evaluated by thermogravimetric analysis.

For the first time, vertically aligned carbon nanotubes (VACNT) were produced using waste cooking palm oil as green starting materials. The synthesis was carried out in a floating-catalyst thermal chemical vapor deposition reactor. Field emission scanning electron microscopy, energy dispersive X-ray, micro-Raman and thermogravimetric analyses, showed that the carbon nanotubes are of excellent quality, comparable to those obtained using conventional carbon sources. Under a typical synthesis condition of 5.33 wt % ferrocence as catalyst and a furnace temperature of 750°C, a mixture of single and multi-walled carbon nanotubes of 85% purity, vertically aligned on a silicon substrate, were produced. Field emission from the VACNT indicated reasonable turnon field at 2.25 V/µm which corresponded to the current density of 10 µA/cm 2 . The threshold field was observed to be about 3.00 V/µm at 1 mA/cm 2 . The maximum current density of 6 mA/cm 2 measured was obtained for 4 V/µm. It is concluded that the VACNT from the reuse of waste material are suitable for applications in flat panel displays and flat lamps.
