Abstract:
A thermodynamic analysis of the carbon nucleation on the metal surface was performed. The master equation for the dependence of critical radius of the carbon nucleus on the reaction parameters, such as the reaction temperature, the catalyst nature, the supersaturation degree of catalyst particle by carbon was obtained. This equation and the phase diagram approach were used for discussion of different scenarios of carbon deposits formation, namely, encapsulated particles, carbon fibers and filaments, multi-wall and single-wall carbon nanotubes. Carbon filament growth via CO disproportionation on cobalt supported catalyst was investigated. Here we demonstrate the possibility to vary the reaction products using the same catalyst just changing the reaction conditions and catalysts pretreatment procedure. For the first time the formation of the carbon filament ropes on Co catalysts was observed.
