Synthesis of carbon nanofibers on an austenitic stainless steel
- 52 Downloads
The surface of the austenitic stainless steel 12Kh18N10T is found to be an effective catalyst for thermal synthesis of carbon nanofibers from acetylene. The morphology of the synthesized material is investigated as a function of the temperature and composition of the working gas mixture. The growth mechanism of carbon nanofibers is proposed. The inference is made that carbide (M 5C2) regions formed in the surface layer upon annealing of the austenitic stainless steel in a hydrocarbon atmosphere are catalytically active zones.
