Be Aware of Transient Dissolution Processes in Co₃O₄ Acidic Oxygen Evolution Reaction Electrocatalysts

must be considered. Hence, this work uncovers the transient character of cobalt dissolution and provides valuable insights that can help to understand the promising stability of cobalt-based materials in already published works and facilitate the knowledge-driven design of novel, stable, abundant catalysts toward the OER in an acidic environment.
