Galvanic replacement reaction: A simple and powerful route to hollow and porous metal nanostructures. Abstract Galvanic replacement reaction provides a remarkably simple and versatile route to metal nanostructures with controllable hollow interiors and porous walls. The key step of this process involves the replacement reaction between a suspension ...

10/11/2017, · The galvanic replacement reaction is thought to start at the sites on the nanocubes with the highest surface energy, dissolving small holes at these active sites once the chloroauric acid is added. The reaction is analogous to a corrosion process, with silver being oxidized at the anode.

The addition of a reducing agent (ascorbic acid) plays a key role in this unconventional mechanistic path, in which ,galvanic replacement, is found to dominate initially when the shell is made of Ag, while seeded growth suppresses transmetalation when a composition of Au:Ag (∼60:40) is reached in the shell, as revealed by quantitative XEDS tomography.

Description. The galvanic replacement reaction is a highly versatile approach for the creation of a variety of nanostructured materials. However, the majority of reports are limited to the replacement of metallic nanoparticles or metal surfaces. Here we extend this elegant approach and describe the galvanic replacement of the liquid metal alloy ...
