【 摘 要 】

Bamboo-like multi-walled carbon nanotubes have been synthesized by an alcohothermal approach between cobaltocene and absolute ethanol at 500 °C. The as-obtained product is characterized by FESEM, TEM, HRTEM and Raman spectroscopy. The results show that the sample consists of a large number of nanotubes with a range of outer diameters from 50 to 100 nm, inner diameter of about 25∼50 nm and several micrometers in length. These nanotubes consist of a linear chain of hollow compartments that are spaced at nearly equal separation of 20 nm for an about 50 nm diameter nanotube. A possible growth mechanism of the bamboo-like carbon nanotubes has been proposed based on the observation of Co particles embedded at the nanotubes' tips.
