Recent advances in activating surface reconstruction for the high-efficiency oxygen evolution reaction

Likun Gao et al.

Summary: Recent advancements in the development of cost-effective and high-efficiency transition metal-based electrocatalysts have led to a better understanding of the dynamic reconstruction of surface structures during electrocatalytic water oxidation, especially the anodic oxygen evolution reaction (OER). Through operando and in situ techniques, it has been found that electrocatalysts undergo surface reconstruction to form actual active species during OER in alkaline solution. By exploring issues such as initiators for surface reconstruction and establishing relationships between structure, composition, and electrocatalytic activity, progress has been made in the rational manipulation of in situ catalyst surface reconstruction for the development of high-efficiency electrocatalysts.
