Morphological changes in Ag nanocrystals triggered by citrate photoreduction and governed by oxidative etching.
The shape of a nanocrystal undergoes significant changes in response to variations in the surrounding environment. In this communication, it has been demonstrated that introduction of citric acid into the system of Ag nanocubes can trigger their shape evolution into nanospheres.
