Abstract
Novel ferrocenyl-imidazolium compounds were synthesized and used as catalyst for the synthesis of shaped carbon nanomaterials (SCNMs). Chemical vapour deposition (CVD) technique was used with acetonitrile and aniline as both nitrogen and carbon source, respectively at 850oC. In this study, the effect of substituents on the ferrocenyl-imidazolium catalyst to produce shaped carbon nanomaterials such as carbon sphere (CS), amorphous carbon (AC), carbon fibre (CF) and nitrogen-doped carbon nanotubes (N-CNTs) were investigated. Bamboo-like N-CNTs were obtained in good yield. Characterization was done using transmission electron microscopy, scanning electron microscopy, high resolution transmission electron microscopy, raman spectroscopy and thermogravimetric studies.
