Abstract

Nanomaterial preparation methods, compositions, and articles are disclosed and claimed. Such methods can provide nanomaterials with improved morphologies relative to previous methods. Such materials are useful in electronic applications.

Claims (10)

1. A method comprising:

providing at least one composition comprising at least one first silver ion and at least one metal oxide halide compound comprising at least one second metal or metal ion comprising at least one element or ion of an element from the International Union of Pure and Applied Chemists (IUPAC) Group 3, the International Union of Pure and Applied Chemists (IUPAC) Group 4, the International Union of Pure and Applied Chemists (IUPAC) Group 5, the International Union of Pure and Applied Chemists (IUPAC) Group 6, or the International Union of Pure and Applied Chemists (IUPAC) Group 7, the at least one second metal or metal ion differing in atomic number from the at least one first silver ion; and

reducing the at least one first silver ion to at least one silver metal nanowire, wherein the at least one silver metal nanowire has a length greater than 10 microns.

2. The method according to claim 1 , wherein the at least one second metal or metal ion has an oxidation state of +4 or greater.

3. The method according to claim 1 , wherein the at least one second metal or metal ion comprises at least one element or ion of an element from IUPAC Group 3.

4. The method according to claim 1 , wherein the at least one second metal or metal ion comprises at least one element f or ion of an element from IUPAC Group 4.

5. The method according to claim 1 , wherein the at least one second metal or metal ion comprises at least one element or ion of an element from IUPAC Group 5.

6. The method according to claim 1 , wherein the at least one second metal or metal ion comprises at least one element or ion of an element from IUPAC Group 6.

7. The method according to claim 1 , wherein the at least one second metal or metal ion comprises at least one element or ion of an element from the International Union of Pure and Applied Chemists (IUPAC) Group 7.

8. The method according to claim 1 , wherein the at least one silver metal nanowire has a diameter between 10 nm and 300 nm.
