Abstract
The present invention relates to a process for preparing CNTs by bringing a carbon source into contact with a multivalent metal and/or metal-oxide-based catalyst deposited on an inorganic substrate having a BET specific surface area of greater than 50 m2/g. The CNTs obtained may be used as agents for improving the mechanical and electrical conductivity properties in polymeric compositions.
