| 摘要: |
| 为研究碳纳米管填充和负载的可控制备,通过沉积负载方法和湿化学填充法制备了不同负载率和填充率的碳纳米管,采用红外光谱仪、X射线衍射仪、高分辨透射电子显微镜和热重分析仪进行了结构表征分析.研究结果表明,负载率和填充率与C和Fe的比例有关.当C与Fe的质量比为4∶1或8∶1时,负载率分别为28.52%或16.17%,填充率分别为11.32%或9.43%. |

| Abstract: |
| To control the loading and filling process,deposition method and wet chemical method were used to prepare Fe2O3-loading multi-walled carbon nanotubes(Fe2O3/MWCNTs) and Fe2O3-containing MWCNTs(Fe2O3@MWCNTs) with different content of Fe2O3,respectively.The Fe2O3/MWCNTs and Fe2O3@MWCNTs were characterized by high resolution transmission electron microscopy(HRTEM),X-ray diffraction(XRD),fourier transform infrared spectroscopy(FT-IR)and thermogravimetry analysis(TG).Results show that the Fe2O3 contents in the Fe2O3/MWCNTs and Fe2O3@MWCNTs systems are related to the mass proportion of C to Fe.When the mass proportion for C to Fe is 4∶ 1 or 8∶ 1,the Fe2O3/MWCNTs with Fe2O3 content will be 28.52 wt.% or 16.17 wt.%,and the Fe2O3@MWCNTs with Fe2O3 content will be 11.32 wt.% or 9.43 wt.%,respectively. |
