| High-Yield Production of Carbon Nanotubes Based on Six-Membered-Ring Growth Mechanism | |
| 摘要: 基于六元环生长机理，以苯为前驱物高产率地制备了多壁碳纳米管。通过调变及优化催化剂的组成和用量、苯通量、生长温度等参量，碳纳米管的最高产率可达859wt%。高分辨透射电子显微镜、扫描电子显微镜、热重-差热分析仪、X射线衍射等分析结果表明，本方法制得的碳纳米管产物的直径约20 nm，纯度高，具有良好的石墨化程度。 | |

| Abstract: A further study on the catalytic synthesis of multi-walled carbon nanotubes (MWCNTs) with benzene precursor is reported based on the six-membered-ring-based growth mechanism. Several influence factors were examined and optimized, including the chemical component of catalysts, catalyst dosage, flux of benzene vapor, and growth temperature. The maximum yield of CNTs was up to 859wt%. Transmission electron microscopy, scanning electron microscopy, thermogravimetry-differential thermal analysis, and X-ray diffraction results show that the products obtained at the optimized condition are the quasi-aligned and well-graphitized CNTs of high purity with a diameter about 20 nm. | |
