Controlling the Shapes of Silver Nanocrystals with Different Capping Agents
TL;DR: This research offers new insights into the role played by a capping agent in shape-controlled synthesis and provides, for the first time, Ag octahedrons as small as 40 nm in edge length for optical and spectroscopic studies.

Shape-Controlled Synthesis of Silver and Gold Nanostructures
TL;DR: A brief account of solution-phase methods that generate silver and gold nanostructures with well-controlled shapes is given in this article, which is organized into five sections: the first section discusses the nucleation and formation of seeds from which nanostructure grow.

Synthesis and optical properties of nanorattles and multiple-walled nanoshells/nanotubes made of metal alloys.
TL;DR: The galvanic replacement reaction between silver and chloroauric acid has been exploited as a powerful means for preparing metal nanostructures with hollow interiors and is further extended to produce complex core/shell nanostructure made of metals by combining the replacement reaction with electroless deposition of silver.

Fabrication of Cubic Nanocages and Nanoframes by Dealloying Au/Ag Alloy Nanoboxes with an Aqueous Etchant Based on Fe(NO3)3 or NH4OH
TL;DR: A two-step procedure for generating cubic nanocages and nanoframes with relatively narrow SPR peaks by controlling the amount of HAuCl4 used for the galvanic replacement reaction and thus the optimization of the percentage of Au in the alloy nanoboxes is described.
Mechanistic studies on the galvanic replacement reaction between multiply twinned particles of Ag and HAuCl4 in an organic medium.
TL;DR: Addition of extra oleylamine was found to be critical to the formation of well-controlled, uniform hollow structures free of AgCl contamination thanks to theformation of a soluble complex between AgCl and oleyamine.
