Nanowire preparation methods, compositions, and articles
View Patent ↗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.
1. A method comprising:
providing a composition comprising at least one silver ion and at least one second non-redox active metal or metal ion, the at least one second non-redox active metal or metal ion differing in atomic number from the at least one silver ion and comprising at least one ion or element from International Union of Pure and Applied Chemistry (IUPAC) Group 13 other than indium or an ion of indium; and
reducing the at least one silver ion to at least one first silver nanowire,
wherein the ratio of the total moles of the at least one second non-redox active metal or metal ion to the total moles of the at least one silver ion is from about 0.0001 to about 0.1.
2. The method according to claim 1 , wherein the at least one second non-redox active metal or metal ion comprises at least one element or an ion of an element in its +3 oxidation state.
3. The method according to claim 1 , wherein the at least one second non-redox active metal or metal ion comprises aluminum or an ion of aluminum.
