Abstract

Metallic lead nanowires were deposited within pores of commercial anodic alumina membranes having an average pore diameterof 210 nm. “Direct” electrodeposition was attempted from 0.1 M Pb NO3 2 aqueous solution with a variable concentration ofH3BO3 as a chelating agent, but it gave unsatisfactory results. An “indirect” two-step deposition procedure was then adopted,consisting of the anodic electrodeposition of -PbO2 nanowires, followed by their in situ reduction to metallic lead. Both theseprocesses occurred at a high rate so that the indirect method led to a complete template pore filling with pure polycrystalline Pbin short times and with a high current efficiency.
