Self-assembling carbon filament ropes formation

Abstract The process of carbon nanotubes and filaments production via catalytic decomposition of CO on SiO 2 -modified Co catalyst was investigated. It was demonstrated that variation in carbon nucleation conditions could be used for the production of different type of carbon deposits over the same catalyst. Carbon nucleation conditions were altered by varying reaction temperature and/or catalyst pretreatment procedure. The formation of carbon filament ropes was observed for the first time.
