摘要：

Multi-walled carbon nanotubes (MWCNTs) were grown on cathode deposit by arc discharge plasma under H-2, Ar, and air ambient environment. The influence of ambient gas pressure on the structure and physical properties of carbon nanotube were compared. Herein, we highlight the influence of ambient environment and pressure to grow high quality carbon nanotubes. Field emission scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and X-ray diffraction were used for structural characterization and yield determination. The result revealed that background gas and pressure were crucial factor for growing highly crystalline and highly graphitic with I-D/I-G ratio 0.237 obtained for MWCNTs' synthesized in H-2 environment with extreme low defects.
