Dealloying of Noble-Metal Alloy Nanoparticles
Nano Letters, 2014 Dealloying is currently used to tailor the morphology and composition of nanoparticles and bulk solids for a variety of applications including catalysis, energy storage, sensing, actuation, supercapacitors, and radiation damage resistant materials. The known morphologies, which evolve on dealloying of nanoparticles, include core-shell, hollow core ...

Effect of dealloying rate on transformation behavior during liquid metal dealloying
Journal of Alloys and Compounds, 2020Abstract Liquid metal dealloying is a new process that can be applied to synthesize non-noble porous materials by preventing oxidation in a utilized metallic melt. The effect of dealloying rate was investigated by electron backscattered diffraction at the reaction layer at various temperatures (600–800 °C) using (FeCo)xNi100−x precursors in a Mg melt.

Mechanisms and Morphology Evolution in Dealloying
Journal of The Electrochemical Society, 2013 Historically, dealloying, the selective dissolution of elemental components from an alloy, has been studied most intensively for binary noble-metal alloys such as Ag-Au, Cu-Au and Zn-Cu. There have been three primacy "mechanisms" proposed to explain ambient temperature dealloying in such systems: "simultaneous" dissolution of both components ...

Probing the Dealloying Critical Potential
Journal of The Electrochemical Society, 2005 One of the important characteristics of dealloying systems is the location of the critical potential which marks the transition from a "passivated" alloy surface to the sustained formation of a bicontinuous porous structure. A steady-state method for accurately determining the dealloying critical potential is compared with the more traditional approach

Evolution of length scales and of chemical heterogeneity during primary and secondary dealloying
Acta Materialia, 2022 We study the evolution of silver-rich regions, or ‘clusters’, during the making of nanoporous gold by dealloying. The clusters, which are remnants of the master alloy that have evaded corrosion, impact the functional behavior of the material. Furthermore,
