Synthesis of Carbon Nanofibers Based on Resol Type Phenol Resin and Fe(III) Catalysts

다국어 초록 (Multilingual Abstract)

The carbon nanofibers (CNFs) used in this study were synthesized with an iron catalyst and ethylene as a carbon source. A concentration of 30 wt % iron(III) acetylacetonate was dissolved in resol type phenol resin and polyurethane foam was put into the solution. The sample was calendered after being cured at 80 °C in air for 24 h. Stabilization and carbonization of the resol type phenol resin and reduction of the Fe3+ were completed in a high-temperature furnace by the following steps: 1) heating to 600 °C at a rate of 10 °C/min with a mixture of H2/N2 for 4 h to reduce the Fe3+ to Fe; 2) heating to 1000 °C in N2 at a rate 10 °C/min for 30 minutes for pyrolysis; 3) synthesizing CNFs in a mixture of 20.1% ethylene and H2/N2 at 700 °C for 2 h using a CVD process. Finally, the structural characterization of the CNFs was performed by scanning electron microscopy and a synthesis analysis was carried out using energy dispersive spectroscopy and X-ray photoelectron spectroscopy. Specific surface area analysis of the CNFs was also performed by N2-sorption.
