Nanopatterning Single-Crystalline Metal Electrodes via Ion Erosion: New Structural Motifs for Model Electrocatalysis.

ABSTRACT: Model studies in electrocatalysis provide valuable insights into complex structure-property relationships and rely heavily on experimental techniques that enable the preparation of electrode surfaces with atomic-scale control over morphology. This work investigates the nanopatterning of single-crystalline metal electrodes through ion erosion. On Pt(111), ion erosion produces surfaces with distinct corrugation, characterized by the formation of erosion pits, an equal proportion of (110) and (100) steps, and a high density of kinks. The obtained structural motifs influence the electrochemical behavior of H/OH adsorption/desorption and surface electrooxidation in a unique manner, illustrating that ion-eroded metal surfaces represent a complex but atomically precise platform for exploring the
