Root characterization of Fe-based catalyzed carbon nanotube forests
Source abstract
Abstract
For the purpose of understanding the process of forming carbon nanotube forests catalyzed by Fe nanoparticles , a combination of ex-situ transmission electron microscopy observations and molecular dynamics simulation methods were used to study the rooting path of C in Fe and its motion evolution mechanism. The results show that C first reacts with Fe to form Fe 3 C, and C enters from Fe (110) crystal plane, thus Fe (110) crystal plane transferring to Fe 3 C (013) crystal plane; then C in Fe 3 C precipitates and grows into carbon nanotubes, and C precipitates from Fe 3 C (013) crystal plane, thus creating the relationship of the direction of carbon nanotubes growth parallel to Fe 3 C (013) crystal plane. The results of the microstructure snapshot over time and radial distribution function calculated by molecular dynamics simulation also show that the motion path of C is the same as the results deduced in the experiment, which confirms the correctness of the results.
