Krijn P. de Jong,John W. Geus +1 more
TL;DR: A review on the growth of nanofibers using metallic particles as a catalyst to precipitate the graphitic carbon can be found in this paper, where the authors summarize some of the earlier literature that has contributed greatly to understand the nucleation and growth of carbon carbon and nanotubes and describe in detail recent progress to control the fiber surface structure, texture, and growth into mechanically strong agglomerates.
