Abstract

High yields of multi-walled carbon nanotubes are synthesized by chemical vapor deposition of acetylene on palladium nanoparticles supported on porous SiO₂. HRTEM results reveal that the carbon nanotubes have novel conical inner structure. By changing the content of palladium in the catalyst, we obtained palladium nanoparticles with different diameter distribution. It was found that the apex angles of cones, the outer diameter and the length have a dependence on the diameter of the palladium nanoparticles. Due to the presence of open graphite layers, these novel carbon nanotubes have fascinating potential for energy storage, filed emission and composites
