Modulation of Spin States in the Second Coordination Shell of Single‐Atom Electrocatalysts for Efficient Water Oxidation
The catalytic performance of single‐atom catalysts (SACs) is critically shaped by their local chemical environment, yet the role of structural features beyond the first coordination shell remains poorly understood. Here, we employ Ir single‐atom‐loaded ZnCo 2 O 4 spinel oxides with calcination‐tuned Co spin‐sta...
