Abstract
Official abstract text for this publication.
Noble metal-coated nanostructures and related methods are disclosed. According to an aspect, a nanostructure may include a structure comprising a base metal. As an example, the structure may be a nanowire. In a more specific example, the structure may be a copper nanowire or a nanowire made of a base metal such as nickel, tin, indium, zinc, the like, or combinations thereof. The base metal structure may be coated with a noble metal that conformally covers the base metal structure. Example noble metals include, but are not limited to, ruthenium, rhodium, palladium, silver, iridium, platinum, and gold. The coating may be made of one or more of the noble metals along with other materials.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: providing a copper nanowire comprising a base metal; and exposing the copper nanowire, to a solution containing ascorbic acid of at least 0.6 molars and a noble metal salt such that oxidation of copper of the copper nanowire is prevented and the noble metal ions in solution are chemically reduced onto and conformally cover the copper nanowire, wherein the copper nanowire and the noble metal covering the copper nanowire are non-porous. 2. The method of claim 1 , wherein the noble metal is one of ruthenium, rhodium, palladium, silver, iridium, platinum, gold, and combinations thereof. 3. The method of claim 1 , wherein the copper nanowire has a length between about 1 micron and about 500 microns. 4. The method of claim 1 , wherein the copper nanowire has a diameter between about 3 nm and about 900 nm.
