Опубликована: Окт. 22, 2024

Abstract Reconstruction of catalysts is now well recognized as a common phenomenon in electrocatalysis. As the reconstructed structure may promote or hamper electrochemical performance, how to achieve designed active surface for highly enhanced catalytic activity through reconstruction needs be carefully investigated. In this review, genesis and effects various processes, such hydrogen evolution reaction (HER), oxygen (OER), carbon dioxide reduction (CO 2 RR), nitrate (NO 3 RR) are first described. Then, strategies optimizing reconstruction, valence states control, phase retention, engineering, poisoning prevention comprehensively discussed. Finally, general rules optimization summarized give perspectives future study. It believed that review shall provide deep insights into electrocatalytic mechanisms guide design pre‐catalysts with improved activity.

ABSTRACT An in-depth understanding of electrocatalytic mechanisms is essential for advancing electrocatalysts the oxygen evolution reaction (OER). The emerging oxide pathway mechanism (OPM) streamlines direct O–O radical coupling, circumventing formation vacancy defects featured in lattice (LOM) and bypassing additional intermediates (*OOH) inherent to adsorbate (AEM). With only *O *OH as intermediates, OPM-driven stand out their ability disrupt traditional scaling relationships while ensuring stability. This review compiles latest significant advances OPM-based electrocatalysis, detailing design principles, synthetic methods, sophisticated techniques identify active sites pathways. We conclude with prospective challenges opportunities electrocatalysts, aiming advance field into a new era by overcoming constraints.
