Synthesis of Multi-walled Carbon Nanotubes from Glycine Max Oil and Their Potential Applications

Abstract

The discovery of carbon nanotubes has created new era in the field of nanotechnology. Spectacular properties of these nanostructured materials, stimulating scientists to peep into this tiny tube with ever increasing curiosity. The immediate challenge is to produce desired structural and characteristic featured carbon nanotubes in large quantities. Chemical vapor deposition is the most popular method of producing carbon nanotubes and it is of low-cost and highly useful technique for mass production of carbon nanotubes. These efforts requires not only chosen technique but also based on the precursor and the catalytic support. Glycine max oil a botanical hydrocarbon, has been found to be effective precursor for the synthesis of multi-walled carbon nanotubes (MWNTs) by Spray Pyrolysis over well dispersed Fe /Mo catalyst supported on silica at 650 °C under Ar atmosphere. As-grown MWNTs were characterized by SEM, HRTEM, Raman spectroscopy and Nitrogen adsorption studies. Raman spectroscopy revels that MWNTs are well graphitized. Dynamic and equilibrium studies of adsorption of Basic brown-4 on MWNTs were also reported.
