Abstract

Particle size is one important parameter of nanocrystals that need to be tightly controlled, owing to its versatility for tailoring the properties and functions of nanocrystals towards various applications. In this article, oxidative etching by hydrogen chloride is employed as a tool to control the size of metallic nanocrystals. As a result of the size control, investigations into the size-dependent plasmonic and catalytic properties of metallic nanocrystals can be investigated. Given that the shape can be kept consistent when tuning the particle size in this system, it enables the systematic investigation of size-dependent properties free of the influence of other factors such as shape effect.
