Web1 nov. 2014 · We show that two types of iron carbide phases, cementite (Fe3C) and Hägg phase (Fe5C2), form spontaneously under carbon nanotube growth conditions. We present direct evidence that the nanoparticles with Fe3C structure are active in nanotube growth (C-C bond formation), while higher carbon contents renders inactive Fe5C2.
