Abstract |
Carbon nanotubes can be obtained from verity of the molecular precursors in chemical vapor deposition (CVD) processes. The growth mechanism of carbon nanotubes (CNTs) still remains unsolved puzzle for the researchers. Therefore, this contribution presents in situ study on the formation of CNTs in CVD process in TGA analyzer. In addition, TGA analysis was applied to estimate the quality of the produced sample. Resonance Raman spectroscopy was used to determine the quality of the final sample and characterize it, e.g. to estimate the diameter of the tubes. High resolution transmission electron microscope with Energy dispersive X-ray spectroscopy was a tool to determine the morphology and elemental composition of the samples, respectively. |
