Carbon Nanotubes Obtained from Natural Gas by CVD

Аннотация

Carbon nanotubes are obtained using chemical vapor deposition (CVD) equipment via the pyrolysis of natural gas in the presence of nanoscale iron. The influence of various parameters on the yield of nanomaterials synthesized is studied, and we find that the yield of nanocarbon increases with an increase in the pyrolysis temperature from 650 to 850°C. At the same time, the introduction of argon, which acts as a buffer gas, into the reactor significantly increases the yield of carbon nanotubes. The samples synthesized are studied by physical methods.
