Abstract

The Chemical Vapor Deposition (CVD) process is the simplest and cheapest method among various synthesis techniques for Carbon Nanotubes (CNT). The work reported here develops a mathematical model to represent CNT synthesis through catalytic chemical vapor deposition (CCVD) with acetylene as the carbon source and iron oxide as the catalyst. The spatial concentration distribution of amorphous carbon (which produces the carbon nanotubes) is obtained by solving the system of governing equations for the momentum, energy and mass transport during CNT formation, using COMSOL Software. The temperature and velocity distributions in the reactor were also obtained from the analysis. The results obtained from the analysis are useful for the optimal design of the CVD furnace.
