Growth and characterization of CNT Forests using Bimetallic Nanoparticles as Catalyst

摘要

The synthesis of Fe, Fe-Pt and Fe-Co nanopaiticles were carried out using the bottom-up polyol process using standard ari free techniques Using these nanoparticles, multiwalled carbon nanotubes were synthesized in an atmospheric pressure plasma enhanced chemical vapor deposition(APPECVD) process with a mixture of helium and acetylene gases. The APPECVD process produced dense carbon nanotube forests that were 30um for Fe, 5|im for Fe-Pt and 80~100um for Fe-Co nanoparticles.
