| 摘 要： | Multi-walled carbon nanotubes were fabricated by chemical vapor deposition with acetylene as carbon source and titanate modified palygorskite as catalyst at high temperature. A part of as-grown nanotubes was partially filled with foreign material in the shape of nanowire by transmission electron microscopy (TEM) observations. The en-capsulated nanowires was single crystalline iron carbide upon selected area electron diffraction(SAED)patterns and X-ray energy dispersive spectrum (EDS) results. Thermal gravimetric analyses (TGA) on the as-grown samples indicated that the yield of carbon nanotubes was largest at 750℃ and the content of amorphous carbon decreased with increasing temperature. Furthermore， the growth mechanism was discussed on the experimental results in the paper. |
