Growth of Carbon Fibers from Copper Dendrite Nanostructures Catalyzed Decomposition of Acetylene

Abstract:

Carbon nanofibers with novel morphology are successfully synthesized by the chemical vapor deposition of acetylene with dendritic copper nanocrystals on Cu electrode as a catalyst. Growth mechanism of sandwich-like and multi-branched carbon fibers is discussed, and the impact of catalyst morphology and growth time on the structure of the carbon nanofibers is investigated. The organic groups and the thermal stability of the as-prepared carbon nanofibers are revealed by Fourier transform infrared spectrum (IR) and thermogravimetric (TG) analysis.
