Abstract:The synthesized methods, growth mechanism, microstructures and physical-chemical properties of one-dimensional carbon nanomaterials (1D-CNMs), including carbon nanotubes and carbon nanofibers, prepared from ethanol flame were reviewed. With the characterization of SEM and TEM images, the well-alignment and nanoscale homojunctions of 1D-CNMs were also reviewed. The results show that the ethanol flame is an efficient process for synthesizing carbon nanotubes and carbon nanofibers, because of its safe fuel storage and simple combustion equipment. It is considered that the future research of 1D-CNMs should be focused on their special microstructures, performances and device building.
