Synthesis of MWNTs using Fe–Mo bimetallic catalyst by CVD method for field emission application

Multiwalled carbon nanotubes (MWNTs) were synthesized by chemical vapor deposition technique using MgO supported bimetallic Fe–Mo catalyst. The role of Mo on the quality of as-synthesized CNTs and their application in field emission has been investigated. The field emission properties of the device fabricated from the CNTs synthesized with Fe–Mo catalyst was found to be better than the similar device prepared with CNTs synthesized with Fe catalyst alone.
