Abstract Regulating the surface electronic structure is crucial for directional design of efficient energy storage materials. However, mechanisms by which alterations in spin microenvironment enhance intrinsic activity remain elusive. In this study, a localized high‐spin environment successfully constructed modifying NH 2 ‐UiO‐66 derivatives with configuration palladium (Pd) nanoparticles. By integrating density functional theory calculations, situ spectroscopy, and multiscale kinetic analysis, it revealed that introduction state Pd creates Lewis acidic on electrode surface, significantly enhances adsorption capacity reactivity electron‐rich intermediates. Moreover, polarization effect increases delocalization d electrons introduces new states near Fermi level, thereby markedly accelerating kinetics electrochemical reactions. Benefiting from mechanism, electrodes exhibit exceptional performance, high specific capacitance 773.3 F g −1 at 1 A . This study offers novel theoretical insights technical pathways fabrication highly active electrodes.
