Abstract
Official abstract text for this publication.
In accordance with the purpose(s) of the present disclosure, as embodied and broadly described herein, embodiments of the present disclosure provide for silver nanowires, methods of making silver nanowires, core-shell nanostructures, methods of making core-shell nanostructures, core-frame nanostructures, methods of making core-frame nanostructures, and the like.
First claim
Opening claim text (preview).
We claim at least the following: 1. A structure comprising: a core-frame nanostructure including a frame around a hollow area within the frame, wherein the frame is a M-Ag alloy, wherein M is selected from the group consisting of Au, Pd, Pt, and Cu. 2. The structure of claim 1 , wherein the core frame nanostructure is selected from the group consisting of: a nanorod, a nanowire, a nano-sized polyhedron, and a nano-sized prism or thin plate. 3. The structure of claim 1 , wherein the nanocube has a length, a width, and a height of about 15 to 250 nm. 4. A method of making a core-frame nanostructure, comprising: providing a silver nanostructure solution containing silver nanostructures, a reducing agent and poly(vinyl pyrrolidone); mixing a first metal precursor solution and a second metal precursor solution with the silver nanostructure solution to produce a core-shell nanostructure; and mixing an etchant with the core-shell nanostructure to remove the silver nanostructure to form the core-frame nanostructure, wherein the core-frame nanostructure includes a frame around a hollow area within the frame, wherein the frame is a M-Ag alloy, wherein M is selected from the group consisting of Au, Pd, Pt, and Cu. 5. The method of claim 4 , wherein the reducing agent is selected from the group consisting of: ascorbic acid, citric acid, formic acid, sodium borohydride, hydrogen gas, aldehydes, alcohols, polyols, carbohydrates, and hydrazine. 6. The method of claim 4 , wherein the etchant is selected from the group consisting of: H 2 O 2 , O 2 , FeCl 3 , Fe(NO 3 ) 3 , K 3 Fe(CN) 6 , and ammonia. 7. The method of claim 4 , wherein the core-frame nanostructure is selected from the group consisting of: a nanorod, a nanowire, a nano-sized polyhedron, and a nano-sized prism or thin plate.
