摘要：

Crystalline structure perfection of carbonaceous nanomaterial (CNM) "Taunir which constitutes the multi-walled nanotubes was studied using a Raman spectroscopy technique. CNM "Taunir was synthesized by MOCVD method. The pristine material, the samples annealed at different temperatures and the samples functionalized by Pt-catalyst nanoparticles were investigated. It has been found that "Taunir belongs to the poorly organized carbon materials but its crystalline structure was observed to order while the annealing temperature increased. D1 and G Raman band (at 1350 and 1580 cm(-1), respectively) intensity ratios were calculated to estimate the crystal structure ordering of CNM "Taunir. The investigation of the influence of functionalization by the catalyst nanoparticles shows that Pt-catalyst precipitation on the surface of MWNTs leads to the increase of the defect band intensity due to an appearance of lattice defects.
