激光辐照对二茂铁掺杂单壁碳纳米管的影响
Effects of Laser Irradiation on the Ferrocene-doped Single-wall Carbon Nanotubes
摘要
Abstract
Utilizing single-wall carbon nanotubes and ferrocene as raw materials,we synthesized ferrocenedoped carbon nanotubos with a high fdling rate through gas phase diffusion method.The obtained materials were confirmed by Raman and infrared spectra.By adjusting laser power on irradiation of samples,obvious changes in the Raman spectra were found,depending on the laser power.The results show that when the laser power is up to 20 mW with the irradiation time of 10 s,some stable new peaks in the Raman spectrum pappeare.In comparative analysis,it was noted that ferrocene formed the iron carbide after laser irradiation and then part of the carbon source transformed into carbon nanotubes and formed double-wall carbon nanotubes.It indicated that the iron carbide was the intermediate products during the conversion of pyrolysis of ferrocene to the inner layer,which was of crucial importance in the comprehension of preparation of doublewall carbon nanotubes by ferrocene-doped carbon nanotubes.关键词
