Development of Indigenous under Gas Arc Discharge System for Gram Scale Growth of Carbon Nano-Tubes

Abstract

In this study indigenous arc discharge setup is designed and fabricated for the gram-scale production of carbon nanotubes. a detailed description of the development and fabrication of the system is given. Carbon nanotubes were synthesized in the presence of Argon gas at 400 -600 Torr Pressure by indigenous setup with different parameter combination like arcing time and role of catalysed is reported analyses of the morphology, composition, and purity were done. The synthesized materials were characterized using scanning electron microscopy, X-ray diffraction (XRD), and Raman spectroscopy. The scanning electron microscopy images show agglomerated tubed fiber like structures in samples from the arc discharge setup, Structural investigations done using powder XRD revealed the presence of the hexagonal crystallographic phase. Furthermore, the presence of the G and 2D bands reveals sp2 hybridization and confirms the presence of carbon nanotubes in samples.
