Carbon nanotube prepared by pulse laser ablation of graphite target in iso-propanol solution

Abstract EN

In this work carbon nanotube was synthesis by pulse laser ablation of graphite target in Iso-propanol solution.

Fourier Transform Infrared Spectroscopy (FTIR) UV-Visible Spectrophotometer and Transmission Electron Microscopy (TEM) were used to study chemical bonding, optical absorption, particle size, structure and morphology of the carbon nanotube.

The FTIR absorption peak at 2335.6, 1647.1 cm-1& 1269.1 cm-1 stretching vibration bond, it is inferred that the C ≡ C C = C and C-C, respectively.

Bonds suggests the formation carbon nanoparticles suspend in this solvent, UV absorption peaks coincide with the electronic transitions corresponding to linear hydrogen–capped polyyne (Cn + 1H2), polyynes are important precursor molecular components in the formation of carbon nanotubes.

The TEM show the aggregation of the carbon nanoparticles with size ranges from (1.66 to 41.6 nm), the structure and morphology of the CNT’s with diameter at range 11.1–46.15 nm and length at range 261.1-592.3 nm.
