Modeling Synthesis of Carbon Nanotubes by Using Injection CVD Reactor

摘要：

Chemical Vapor Deposition (CVD) is one of the most efficient methods of synthesizing carbon nanotubes (CNTs). This paper presents a model to simulate synthesizing CNTs by using xylene as a carbon source and ferrocene as a catalyst precursor. The model comprises of the conservation equations of mass, momentum, heat and the mass fractions of the reactant and product species, and chemical reaction. None-uniform distribution of the catalyst particles on the substrate is dealt with by an approximation. It allows determination of the velocity field, temperature field, distribution of reactant and product species as well as carbon deposition rates. The deposition rates of CNTs predicted by model are coincident with the experimental ones basically.
