Abstract

Preliminary in situ investigation of the CNT growth process and its mechanism was performed. Filamentous growth was clearly seen at low temperature in propylene. However, multiwall tubes were observed to form at temperatures as low as 450°C in acetylene, with catalyst observed both at the center and at the tips of the tubes. Remarkably, a crystalline cubic carbon phase appeared to form on the walls of the growing MWNTs.
