摘要：

The effects of catalyst concentration on the synthesis of vertically aligned carbon nanotubes (VACNTs) using ferrocene as catalyst and palm oil as bio-hydrocarbon source in thermal chemical vapor deposition (CVD) method were studied. The CVD reaction took 30 minutes followed by 10 minutes annealing process at various ferrocene concentration; 0.66, 1.33, 2.66, 3.99, 5.33, 6.66 and 7.99 wt% at fixed synthesis temperature 750 degrees C. The VACNTs were characterized by field emission scanning electron microscopy (FESEM) and Raman spectroscopy. The growth rate, the diameters, and the degree of crystalinity of the VACNTs were found to be dependent on the catalyst concentration.
