The paper explores the structural factors contributing to catalyst deactivation, elucidating the underlying mechanisms with detailed case studies of hydrogen and oxygen evolution reactions. Specifically, the in situ assessment and characterization techniques are highlighted, which can offer a collective understanding of catalyst deactivation. Building on these insights, recent advances in mitigating catalyst deactivation are introduced, from innovative catalyst designs to advanced electrode engineering. The review concludes by emphasizing the necessity for universal test protocols for deactivation and integrating evidence from diverse in situ measurements, aiming to provide introductive guidance examining the complexities of electrocatalyst deactivation.

At the 244th Electrochemical Society (ECS) Meeting, Prof. Weiran Zheng delivered an oral presentation on “How to perform iR compensation in electrocatalytic study”.
