Abstract
For production of multiwall carbon nanotubes (MWNT) by catalytic chemical vapour deposition (CCVD) different transition metals supported on amorphous or crystalline oxides such as silica, alumina or zeolites were used. In several cases both the productivity of catalysts and the quality of MWNT are improved by using bimetallic catalysts such as Co‐Fe, Co‐V etc. In this publication we report the results in comparison of mono and bimetallic catalysts of Co, Fe, Ni and V supported on alumina, zeolite 13X‐FAU and zeolite ZSM‐5‐MFI.
