Strain‐Driven Surface Reconstruction During the Alkaline Oxygen Evolution Reaction: a Model Thin‐Film Study

Advanced Materials, EarlyView.
ABSTRACT Dynamic surface reconstruction critically governs the performance and durability of oxide‐based electrocatalysts for the oxygen evolution reaction (OER), yet controlling this process under operating conditions remains challenging. Here, we demonstrate that lattice strain regulates the extent of surface reconstruction in perovskite oxides by ...
