Bulk Synthesis and Characterization of Multiwalled Carbon Nanotubes by CVD method
Keywords:
Multiwalled carbon nanotubes, catalyst, chemical vapor deposition, energy.Abstract
Multiwalled Carbon nanotubes (MWCNTs) were effectively synthesized by Chemical vapor deposition (CVD) using metallic catalyst Fe-MgO with growth temperature 700 °C and pyrolysis time at 30 min. The synthesized MWCNTs were characterized by X-ray diffraction (XRD) pattern confirmed the crystalline structure like hexagonal structure (002) plane. SEM morphology of MWCNTs are having in the diameter range of 50-80 nm and length is up to few µm. From the TEM images shown that the MWCNTs with evidence of clear graphitic walls around 15 layers were clearly visualized in 5nm scale. Fe-MgO as good catalytic growth for MWCNTs and also well supported to enhance the bulk production. In future, pure carbon nanotubes and MWCNTs composite materials have been apply for energy storage applications.
