ENTANGLED MULTI-WALLED CARBON NANOTUBES FROM CITRUS LIMONUM OIL

Multi-walled carbon nanotubes have been synthesized by simple method of spray pyrolysis using Citrus limonum oil
on Fe/Mo catalyst supported on silica and their characteristics were investigated. Citrus limonum oil: a plant based
precursor was used as a carbon source. Multi-walled carbon nanotubes were synthesized using Citrus Limonum oil
at different temperatures ranging from 550 °C to 750 °C. The characteristics of MWNTs markedly changes such as
crystallinity, diameter, etc., confirmed by scanning electron microscope (SEM), high resolution transmission
electron microscope (HRTEM), X-ray diffraction analysis (XRD) and Raman spectral studies. The HRTEM and
Raman spectroscopic studies confirmed the evolution of MWNTs with the outer diameter between 20 and 40 nm.
The bimetallic catalyst of Mo and Fe supported on silica as supporting materials to produce quality, quantity and
uniformity of MWNTs.
