Abstract Design of active and stable electrocatalysts for the oxygen evolution reaction (OER) requires in‐depth understanding of the electrocatalyst properties and interfacial structural dynamics during OER. One of the essential insights for advanced electrocatalyst design is vivid understanding of the drivers and mechanisms of dissolution of electrocatalysts. In this work we analyze some important aspects of electrocatalyst dissolution during OER, to deepen and advance our understanding of activity‐stability relations and relevant stability descriptors.
