Filamentous carbon is a carbon-containing deposit structure that refers to several allotropes of carbon, including carbon nanotubes, carbon nanofibers, and microcoils.[1][2][3] It forms from gaseous carbon compounds.[1] Filamentous carbon structures all contain metal particles. These are either iron, cobalt, or nickel or their alloys. Deposits of it also significantly disrupt synthesis gas methanation.[4] Acetylene is involved in a number of method of the production of filamentous carbon. The structures of filamentous carbon are mesoporous and on the micrometer scale in dimension. Most reactions that form the structures take place at or above 280 °C (536 °F).
Filamentous carbon's applications include cleaning up spills of crude oil and the creation of strong and lightweight composites. Filamentous carbon also has significantly different thermodynamic properties from graphite, another form of carbon. However, filamentous carbon partially consists of graphite sheets.
