Helical carbon nanofibers (HCNFs) with the diameter less than 80 nm were produced through catalytic chemical vapor deposition by acetylene pyrolysis with a catalyst derived from the decomposition of copper tartrate at 270 degrees C. Thermogravimetric and differential scanning calorimetry, x-ray diffraction, atomic force microscopy, scanning electron microscopy and transmission electron microscope were used to characterize the reaction products. The results show that heating rate of copper tartrate has a significant effect on catalyst particle size and fiber morphology. Three different kinds of fiber morphologies can be obtained at the heating rate of 1-10 degrees C min(-1). The formation mechanism of carbon nanofibers indicates that catalyst particles with symmetric shape and small size were suitable for the growth of regular HCNFs.

Abstract: Helical carbon nanofibers (HCNFs) with the diameter less than 80 nm were produced through catalytic chemical vapor deposition by acetylene pyrolysis with a catalyst derived from the decomposition of copper tartrate at 270 ¡ãC. Thermogravimetric and differential scanning calorimetry, x-ray diffraction, atomic force microscopy, scanning electron microscopy and transmission electron microscope were used to characterize the reaction products. The results show that heating rate of copper tartrate has a significant effect on catalyst particle size and fiber morphology. Three different kinds of fiber morphologies can be obtained at the heating rate of 1-10 ¡ãC min-1. The formation mechanism of carbon nanofibers indicates that catalyst particles with symmetric shape and small size were suitable for the growth of regular HCNFs.
