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.
