Capping agent replacement induced self-organization of ultrathin nanowires: a new and general approach for fabricating noble metal nanoporous films with small ligament sizes

摘要

Ultrafine ligament noble metal nanoporous films are successfully fabricated by self-organization of ultrathin nanowires. The replacement of weak binding capping agent Triton X-114, used for stabilizing nanowires, by Cl~- is claimed for this self-organization. Our method is also applicable for synthesizing other hierarchical nanostructure-like hybrid nanoporous films.
