Abstract

Understanding the mechanism of the oxygen evolution reaction (OER) represents a bottleneck in designing efficient energy storage schemes based on water splitting. However, identifying the mechanism experimentally has proven a grand challenge. This could be due to the diverse nature of OER intermediates. Recent progress in operando/in situ characterizations has provided an unprecedented understanding of the OER mechanisms concerning active site identification, as well as other OER mechanisms. On this basis, we offer a comprehensive discussion on experimental evidence for identifying OER intermediates experimentally, aligning them with theoretical calculations in designing future green energy systems. Finally, some perspectives that are anticipated to be beneficial to addressing the current challenges in operando/in situ monitoring of active site identification and understanding of the underlying mechanisms of OER electrocatalysts are presented. This review aims to provide new insights into the rational design of OER catalytic materials and offers a complete understanding of OER mechanisms.
