Abstract A synthesis technique based on an anodic aluminium oxide (AAO) template was developed to synthesize carbon nanofibres via thermal decomposition of acetylene using nickel as a catalyst. The structure and morphology of the nanofibres were studied with scanning electron microscopy, transmission electron microscopy and Raman spectroscopy. It was found that most of the carbon nanofibres have a diameter of 150 nm, similar to that of the template nanopores. Also, they have novel shapes. Their electron field emission property was measured and a threshold field of 6.6 MV m −1 was observed. Copyright © 2004 John Wiley & Sons, Ltd.
