Carbon Nanotube Prepared by Pulse Laser Ablation of Graphite Target in Iso-Propanol Solution


In this work carbon nanotube was synthesis by pulse laser ablation of graphitetarget 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, structureand 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 nanoparticlessuspend in this solvent, UV absorption peaks coincide with the electronictransitions corresponding to linear hydrogen – capped polyyne (Cn+1H2), polyynesare important precursor molecular components in the formation of carbonnanotubes. The TEM show the aggregation of the carbon nanoparticles with sizeranges from (1.66 to 41.6 nm), the structure and morphology of the CNT’s withdiameter at range 11.1 – 46.15 nm and length at range 261.1 - 592.3 nm.
