Rapid spontaneous alloying between Pd nanocubes and spherical or triangular Ag nanoparticles was studied in an aqueous solution at ambient temperature using transmission electron microscopy (TEM), TEM-energy-dispersed X-ray spectroscopy (EDS), XRD, and UV-Vis spectroscopy of product particles. The results show that alloying occurs between Ag particles and Pd cubes and finishes within a few seconds, preserving the cubic shape with maximum Ag content of approximately 22%.

Rapid transformation from spherical nanoparticles, nanorods, cubes, or bipyramids to triangular prisms of silver with PVP, citrate, and H2O2.
TLDR
Results show that prisms can be prepared without addition of PVP, although it is useful to synthesize smaller monodispersed prisms, and that rapid prism formation starts from the consumption of spherical Ag particles because of shape-selective oxidative etching by H(2)O(2).
