High‐Yield Synthesis of Ultrathin Metal Nanowires in Carbon Nanotubes

Abstract

Filling the tube: Ultrathin metal nanowires with diameters of single atoms (ca. 1.7 nm) were synthesized in high yield by using a nanofilling reaction using the nanospace of carbon nanotubes (CNTs). As the nanowires are protected by the wall of the CNTs, they resist oxidation and structural disintegration even under ambient conditions.
