Anion-Directed Engineering of High-Entropy Layered Double Hydroxides for Oxygen Evolution Catalysis

. They also demonstrate exceptional performance as anode catalysts in AEMWE. Density functional theory calculations reveal that cation vacancies combined with adsorbed sulfate ions reduce the reaction energy barrier, accounting for the superior activity. These results underscore the pivotal role of anions in tuning the structure-function relationship of high-entropy catalysts and provide a efficient strategy for designing high-performance water oxidation electrocatalysts.
