The Characteristics of Natural Occurred Carbon Nanotubes - from Transmission Electronic Microscopy and Raman Spectroscopy

Abstract:

Article Preview

The natural carbon nanotubes(CNTs) have been found in the Sujiquan graphite ore deposit and the high resolution transmission electronic microscopy and the micro laser Raman Spectrum have been used to study their structure. The length of CNTs from n nm to 300nm and width vary between 0.n nm and 30 nm. The RBMs at 462cm-1 in the first-order Raman spectrum of natural CNTs should originate from the inner diameters of 0.5nm. The obvious characteristic peak is at 1343.41 cm-1and 1577.08 cm-1 indicating high graphitization degree. The S1~S4 peaks also found in the second-order Raman spectra.
