Patent attributes
Disclosed is a process for producing metal nanowires having a diameter or thickness from 2 nm to 100 nm, the process comprising: (a) preparing a source metal particulate having a size from 50 nm to 500 μm, selected from a transition metal, Al, Be, Mg, Ca, an alloy thereof, a compound thereof, or a combination thereof; (b) depositing a catalytic metal, in the form of nanoparticles or a coating having a diameter or thickness from 1 nm to 100 nm, onto a surface of the source metal particulate to form a catalyst metal-coated metal material, wherein the catalytic metal is different than the source metal material; and (c) exposing the catalyst metal-coated metal material to a high temperature environment, from 100° C. to 2,500° C., for a period of time sufficient to enable a catalytic metal-assisted growth of multiple metal nanowires from the source metal particulate.
