Published: April 14, 2025

Abstract Single‐atom site electrocatalysts (SACs), with maximum atom efficiency, fine‐tuned coordination structure, and exceptional reactivity toward catalysis, energy, environmental purification, have become the emerging frontier in recent decade. Along significant breakthroughs activity selectivity, limited stability durability of SACs are often underemphasized, posing a grand challenge meeting practical requirements. One pivotal obstacle to construction highly stable is heavy reliance on empirical rather than rational design methods. A comprehensive review urgently needed offer concise overview progress stability/durability, encompassing both deactivation mechanism mitigation strategies. Herein, this first critically summarizes degradation induction factors at atomic‐, meso‐ nanoscale, mainly based but not oxygen reduction reaction. Subsequently, potential stability/durability improvement strategies by tuning catalyst composition, morphology surface delineated, including robust substrate metal‐support interaction, optimization active stability, fabrication porosity modification. Finally, challenges prospects for discussed. This facilitates fundamental understanding provides efficient principles aimed overcoming difficulties beyond.
