Abstract
Nanomaterial preparation methods, compositions, and articles are disclosed and claimed. Such methods can provide nanomaterials with improved morphologies and reduced nitric oxide co-production relative to previous methods. Such materials are useful in electronic applications.
Claims8
A method comprising:
- providing at least one solution comprising at least one first reducible metal ion and at least one second metal or metal ion comprising at least one lanthanide metal or ion of a lanthanide, the at least one second metal or metal ion differing in atomic number from the at least one first reducible metal ion;
- reducing the at least one first reducible metal ion to at least one first metal nanowire;
- and
- further comprising co-producing nitric oxide at a ratio A of moles nitric oxide co-produced per mole of the at least one first reducible metal ion reduced,
- wherein the ratio A is less than 40% of a ratio B, where B is the maximum instantaneous ratio of moles nitric oxide co-produced per mole of the at least one first reducible metal ion reduced when reducing the at least one first reducible metal ion in the presence of Fe2+ ions.
