Supercritical Fluid Fabrication of Metal Nanowires and Nanorods Templated by Multiwalled Carbon Nanotubes

Abstract

Metal nanorods and nanowires (see Figure) have been synthesized using multiwalled carbon nanotubes (MWCNTs) as templates and supercritical CO 2 as the reaction medium. This rapid, direct, and clean approach can also be used to fabricate other metal/CNT composites and to coat the CNTs with metal films or nanoparticles.
