Abstract EN
The effect of alumina and magnesia supported germanium (Ge) nanoparticles on the synthesis of carbon nanotubes (CNTs) using the chemical vapor deposition (CVD) method in atmospheric pressure was investigated.
The TEM micrographs confirmed the formation of carbon nanotubes, and the field emission scanning electron microscopy (FESEM) analysis suggested a tip-growth mechanism for the grown carbon nanotubes.
The X-ray diffraction (XRD) pattern indicated a graphitic nature of the carbon nanotubes.
The obtained CNTs using Ge nanoparticles supported by MgO resulted in a higher degree of graphitization than the CNTs obtained using Ge nanoparticles supported by Al2O3.
Raman spectroscopy analysis of the CNTs confirmed the presence of radial breathing modes (RBM), which verified the formation of CNTs.
High frequency Raman analysis demonstrated that the degree of graphitization of the synthesized CNTs using magnesia supported Ge nanoparticles is higher than that of the alumina supported Ge nanoparticles with the values of (ID/IG) ratios equal to 0.45 and 0.73, respectively.
