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.

The electrochemical CO2 reduction reaction (eCO2RR) is a promising approach for converting to useful chemicals and, hence, achieving carbon neutrality. Though high selectivity and activity of products have been achieved recently, all are reported in neutral or alkaline electrolytes. Although these electrolyte media give activity, they face the major challenge low utilization because carbonate formation, which lowers overall efficiency process. Conducting eCO2RR acidic can help overcome issue formation hence increase efficiency. However, there many challenges associated with eCO2RR.
