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