摘要：

A perfect carbon nanotube with two closed ends consisting of graphitized carbon was experimentally observed. The large carbon nanotube, with a diameter of 187 nm and a length of 1.2 mum, was synthesized by pyrolysis of iron(II)phthalocyanine (FePc) under an Ar/NH3 flow at 900 degreesC on a nickel substrate. The structure and composition of the nanotube were determined by high-resolution transmission electron microscopy and electron energy loss spectroscopy. The carbon nanotube seems to grow spontaneously by some autocatalytic process.
