Abstract

Few-wall carbon nanotubes were synthesized by methane/acetylene decomposition over bimetallic Fe-Mo catalyst with MgO (1:8:40) support at the temperature of 900°C. No calcinations and reduction pretreatments were applied to the catalytic powder. The transmission electron microscopy investigation showed that the synthesized carbon nanotubes [CNTs] have high purity and narrow diameter distribution. Raman spectrum showed that the ratio of G to D band line intensities of IG/ID is approximately 10, and the peaks in the low frequency range were attributed to the radial breathing mode corresponding to the nanotubes of small diameters. Thermogravimetric analysis data indicated no amorphous carbon phases. Experiments conducted at higher gas pressures showed the increase of CNT yield up to 83%. Mössbauer spectroscopy, magnetization measurements, X-ray diffraction, high-resolution transmission electron microscopy, and electron diffraction were employed to evaluate the nature of catalyst particles.

摘要

通过在900°C温度下，在具有MgO（1:8:40）载体的双金属Fe-Mo催化剂上进行甲烷/乙炔分解反应，合成了少壁碳纳米管。催化粉末未进行煅烧和还原预处理。透射电子显微镜研究表明，合成的碳纳米管（CNTs）具有高纯度和窄直径分布。拉曼光谱表明，G带与D带谱线强度之比IG/ID约为10，低频范围内的峰归因于对应小直径纳米管的径向呼吸模式。热重分析数据表明不存在无定形碳相。在较高气压下进行的实验表明，碳纳米管产率提高到了83%。采用穆斯堡尔光谱、磁化测量、X射线衍射、高分辨率透射电子显微镜和电子衍射来评估催化剂颗粒的性质。
