ABSTRACT

The fast condensation of gaseous carbon-related species results in the formation of novel nanomaterials, i.e., silicon carbide nanowires, carbon nanotubes, and graphene flakes. To produce gaseous building blocks of nanomaterials, this chapter utilizes either combustion synthesis (CS) or plasma activation of reactants. CS requires a reactor that is resistant to drastic process parameters: temperature and high-pressure gradients and chemically aggressive reaction medium. The chapter proposes the high-energy synthesis of carbon-related nanostructures. The attractiveness of plasma processes stems, in general, from high energy densities in the reaction zone resulting in high precursor flow rates and increased temperatures, with both factors causing significant reductions in nanomaterials’ growth reaction time. It is crucial to understand the phenomena occurring during the synthesis process and the mechanisms for creating and maximizing the amount of nanofibers synthesized, as well as other various characteristics of the products obtained in high-energetic conditions.
