Dual roles of underpotential deposition in the synthesis of tetrahexahedral Pd-Ag alloy nanocrystals

Chem Commun (Camb). 2020 Nov 26;56(94):14849-14852. doi: 10.1039/d0cc06090a.

Abstract

Tetrahexahedral Pd-Ag alloy nanocrystals enclosed by high-index {520} facets with enhanced electrocatalytic activity have been synthesized using an Ag(i)-assisted growth protocol. The underpotential deposition of Ag plays dual roles in the formation of tetrahexahedral nanocrystals: it not only stabilizes the high-index {520} facets, but also facilitates the formation of Pd-Ag alloys.
