Progress in In Situ Research on Dynamic Surface Reconstruction of Electrocatalysts for Oxygen Evolution Reaction

Renewable energy and sustainable development have attracted considerable attention due to the rapid growth of consumption environmental pollution. The further electrocatalytic water splitting can promote application next-generation systems. However, lack an in-depth understanding dynamic restructuring process occurring on catalyst surface in oxygen evolution reaction (OER) has limited improvement OER-related theories. Therefore, real-time monitoring analysis reconstruction a great significance for deeply intrinsic catalytic mechanism OER. Herein, latest progress situ methods characterizing various transition metal-based OER electrocatalysts recent years is summarized. Many commonly used characterization techniques been reviewed reveal correlation between structure, reconstruction, activity.
