Synthesis of Carbon Nanofibers on C-Fiber Textiles by Thermal CVD Using Fe Catalyst

Abstract:

This research was conducted to synthesize carbon nanofibers on C-fiber textiles by thermal CVD using Fe catalyst. The substrate which was a carbon textile consisting of non woven carbon fibers and attached graphite particles, was oxidized by nitric acid before the deposition process. Hydroxyl groups were created on the C-fiber textile due to the oxidization step. Fe (III) hydroxide was subsequently deposited on the oxidized surface of the C-fiber textile. To deposit ferric particles two different methods were tested: i) deposition-precipitation, ii) dip-coating. For the experiments using both type of catalyst deposition the weight ratio of Fe to C-fiber textile was also varied. Ferric particles were reduced to iron after deposition by using H₂/N₂ gas and CNFs were grown by flowing ethylene gas. Properties of carbon nanofibers created like this were analyzed through Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), N₂-sorption (BET), X-Ray Diffraction (XRD), and X-ray Photoelectron Spectoscopy (XPS). In the case of deposition-precipitation method the result shows that the diameter of carbon nanofibers grew up to 40~60nm and 30~55nm at which the weight ratios of Fe catalyst to C-fiber textiles are 1:30 and 1:70 respectively. If Fe particles were deposited by dip-coating method, the diameter of carbon nanofibers grew up to 40~60nm and 25~30nm for the ratios of Fe catalyst to C-fiber textiles 1:10 and 1:30.
