Zhiqiang’s paper on JACS

Zhiqiang’s paper about Cu@Au core−shell nanowires has been published on JACS. Copper nanowire networks are considered a promising alternative to indium tin oxide as transparent conductors but are not stable in air. In this work, we developed the synthesis of ultrathin Cu@Au core−shell nanowires using trioctylphosphine as a strong binding ligand to prevent galvanic replacement reactions. The epitaxial overgrowth of a gold shell with a few atomic layers on the surface of copper nanowires can greatly enhance their resistance to heat (80 °C), humidity (80%) and air for at least 700 h, while their optical and electrical performance remained similar to the original high-performance copper.
