CNT Production by CCVD
Catalytic Chemical Vapour Deposition (CCVD)
- Growth of CNT on catalyst (usually particles)
- Used for MWNT and SWNT
- High purity, high aspect ratio, but low amounts of catalyst impurities unavoidable
- Reactor technologies:
- Fluidized bed (Baytubes® Process)
- Rotary kiln
- Floating catalyst
Mechanism for the nucleation and growth of a carbon nanotube from hydrocarbon catalyzed by a (co-precipitated) metal catalyst
