Striking Influence of the Catalyst Support and Its Acid–Base Properties: New Insight into the Growth Mechanism of Carbon Nanotubes

Gabor Laurenczy, Jin Won Seo, Arnaud Magrez, Donatello Acquaviva, Juan Carlos Andresen, Rita Smajda, Endre Horvath

In the accepted mechanisms of carbon nanotube (CNT) growth by catalytic chemical vapor deposition (CCVD), the catalyst support is falsely considered as a passive material whose only role is to prevent catalytic particles from coarsening. The chemical chang ...
