Abstract

Chemical vapor deposition (CVD) and flame fragments deposition (FFD) are two techniques to synthesize CNTs from propanol and liquefied petroleum gas (LPG) respectively. The two synthesized CNTs were analyzed by using high resolution-transmission electron microscopy HR-TEM in order to make compare between the two types CNT/CVD and CNT/FFD. The HR-TEMs images showed that the two types were few walled carbon nanotubes FWCNTs with 0.6- 1.2 μm and 1.1- 2.7 μm in length for CNT/CVD and CNT/FL respectively. The outer and inner diameter were referred to thickness 2- 4 sheet of graphene for CNT/CVD while CNT/FFD was 2-3 sheets of graphene. The analysis indicates that Raman spectroscopy were influence with impurities when shows reduceing in the intensities of G, D and RBM bands.
