Abstract
CNTs based nanocomposites are the most encouraging materials in field of nano-photonics, energy storage devices, optoelectronics, gas sensing, and photo-catalysis owing to their excellent properties. In this research work, spectroscopic study of functionalized multiwalled carbon nanotubes (FMWCNTs) nanocomposites with different wt% of SnO2 nanoparticles (NPs), synthesized via easy and economical dispersion route is investigated. X-ray diffraction (XRD) and Raman spectroscopy identified the structural defects present in the SnO2/FMWCNTs nanocomposites whereas X-ray photoelectron spectroscopy (XPS) is exploited to expose the chemical composition as well as valence state of SnO2/FMWCNTs nanocomposite. Field emission scanning electron microscope (FESEM) micrographs exhibit the tubular morphology while transmission electron microscope (TEM) analysis confirms the attachment of SnO2 NPs on outer surface of FMWCNTs. The proximity of different functional groups on the FMWCNTs and SnO2/FMWCNTs nanocomposites are validated through Fourier Transform Infra-red (FTIR) spectroscopy.
