Abstract

This paper aims to synthesize MWCNTs by using the spray pyrolysis technique. The X-ray diffraction technique is done to accomplish structural characterizations and optical characterizations are done by using UV–visible spectro-photometry, Fourier-transform spectroscopy. A scanning electron micrograph has studied the morphology of these nanotubes. The SEM images show the tube-shape structure of MWCNTs, and XRD peaks at 26.04°, 44.12°, and 53.81° confirm that the MWCNTs were successfully synthesized by spray pyrolysis and have average particle size 8.9 nm. Optical bandgap found as ∼4.28 eV using Tauc’s plot.
