Abstract

Surface strontium (Sr) enrichment in perovskite oxides has long been associated with degraded oxygen electrocatalysis. Now, atomically precise control of SrO coverage under operating conditions shows a volcano-shaped structure–activity relationship, revealing that a single SrO surface layer maximizes oxygen incorporation, with further analysis showing how surface termination influences the mechanism.

原子层滴定法揭示了钙钛矿氧化物中氧掺入的最佳SrO终止

钙钛矿氧化物中锶（Sr）的表面富集一直与氧电催化降解有关。现在，在操作条件下对SrO覆盖的原子精确控制显示出火山状的结构-活性关系，揭示了单个SrO表表层最大限度地增加了氧气的结合，并进一步分析了表面终止如何影响机制。
