Abstract
Facing the pyramids by etching forward: Concave palladium polyhedra have been successfully prepared by selectively etching the {100} facets in situ by I(-) ions. Due to the presence of a high density of atomic steps and surface relaxation, the concave palladium polyhedra exhibit an enhanced electrocatalytic activity towards ethanol oxidation.
