Synthesis and Characterization of Nanoporous Gold Nanowires
Abstract
We report on a two-step process for the fabrication of nanoporous nanowires. The fabrication process involves electrochemical deposition of a single-phase binary alloy into a nanoporous template, followed by subsequent etching of the less noble component. These particles are characterized by diameters of 20 nm or larger, lengths of up to tens of microns, and a porous structure with controlled pore dimensions. In contrast to conventional solid nanoparticles, nonporous nanowires have a high surface area and a well-defined pore morphology. Furthermore, nanoporous segments can be incorporated into multisegment nanorods or nanowires. Here, we demonstrate the fabrication of nanoporous gold (NPG) nanowires and multisegment nanowires incorporating Au/NPG layers and Pt/NPG layers.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
