Method for synthesizing metal nanowires in anodic alumina membranes using solid state reduction

摘要

The invention proposes a novel method for the fabrication of regular arrays of MNWs using solid-state reduction (SSR). Using this method copper (Cu), silver (Ag), and palladium (Pd) nanowire (NWs) arrays were synthesized using anodic alumina membranes (AAMs) as templates. Depending on the metal loading used the NWs reached different diameters.

1. A method for synthesizing metal nanowires in anodic alumina membranes using solid state reduction comprising:
depositing dropwise a solution of a metal precursor over a surface of an anodic alumina membrane to form a deposited surface; drying said deposited surface; reducing said metal precursor by spreading NaBH4 on a surface of said anodic alumina membrane opposite to the surface previously deposited with said solution of a metal precursor; removing said NaBH4 by immersing said membrane in water; and dissolving the membrane by placing said membrane in a solution of sodium hydroxide.
