“…Despite the first observation of porosity evolution in np-Au during early 1990s (an early report of pattern formation during dealloying dates back to 1920s [ 23 ]), the actual mechanisms that played a pivotal role were not well-studied until more than a decade later. Erlebacher et al used an elegant kinetic model to describe the nanoporosity formation in a Au-Ag alloy, using only diffusions of silver and gold, and a dissolution of silver [ 24 , 25 ].…”

Nanoporous gold (np-Au) has intriguing material properties that offer potential benefits for many applications due to its high specific surface area, well-characterized thiol-gold surface chemistry, high electrical conductivity, and reduced stiffness. The research on np-Au has taken place on various fronts, including advanced microfabrication and characterization techniques to probe unusual nanoscale properties and applications spanning from fuel cells to electrochemical sensors. Here, we provide a review of the recent advances in np-Au research, with special emphasis on microfabrication and characterization techniques. We conclude the paper with a brief outline of challenges to overcome in the study of nanoporous metals.

“…An example is the depletion gilding by selective leaching of Cu from Au-Cu alloys. 519 It is observed in technologically important alloy systems. Later, this leaching process was also extended to other systems, such as the porous RANEY s nickel, 520 macroporous ceramic CaZrO 3 521 and titania.…”

“…Selective dissolution has a long and rich history 3 . The chemical treatment known as depletion gilding, for instance, selectively dissolves a non-gold element near the surface of a less expensive alloy such as Au-Cu, leaving behind a surface of pure gold.…”
