Abstract

This present work describes exploring cost-effective a natural renewable Environment-friendly green precursor for the synthesis of Multi-walled carbon nanotubes (MWCNTs) using methyl ester of Zingiber officinale oil over Fe-Co impregnated alumina support at 850°C under N2 atmosphere. The characterization of the as-grown carbon materials was analyzed by Scanning electron microscopy (SEM), Highresolution transmission electron microscopy (HRTEM), XRD and Raman spectroscopic analysis. The bimetallic catalyst of Fe and Co supported on alumina gel particles improves the quality and uniformity in diameters of CNTs. The diameters of as-synthesized nanotubes are in the range of 22 nm to 24 nm.
