Abstract
The invention relates to a CCVD method for producing tubular carbon nanofibers on a support by catalytically depositing carbon out of the vapor phase. The inventive method is characterized in that a catalyst layer, which is deposited without current and which is based on nickel or cobalt, is applied to the support at least in places. Said catalyst layer is thermally activated before depositing carbon out of the vapor phase in a reducing atmosphere.
