“…Most of the work related to electrofaceting of noble metals has been performed on platinum [7,8,9,10,11,12,13] and gold [14,15], and a mechanism for their formation has been furnished. Several processes of electrodissolution and electrocrystallization are often involved in electrofaceting, which occur with a progressive transformation that leads to the formation of stepped surfaces showing a preferred crystallographic orientation [10,16,17]. The electrofaceted electrodes have been characterized by cyclic voltammetry [7,13,16,17], metal underpotential deposition (upd) [4,9], scanning electron microscopy (SEM) [18] and scanning tunneling microscopy (STM) [4,19].…”
