CNT Synthesis by CVD on Moving substrate

example section example

4 materials2 process steps

Carbon nanotubes are synthesized by chemical vapor deposition on a constantly moving substrate coated with metal catalyst (e.g., Fe, Ni, Co, Cu). A carbon source (e.g., CO, acetylene, ethylene, methane) and carrier gas (e.g., Ar, He, N₂) are flowed into the chamber. The substrate moves sequentially through catalyst deposition, CNT formation, separation, and collection steps. Temperature range for multi-walled CNTs is 600–900°C; for single-walled CNTs is 700–1100°C. The synthesized CNTs are subsequently converted to graphene nanoribbons, graphene nanoplatelets, or mixtures thereof.
