Electron Pumping Overcomes Spin-Crossover Barrier to Lock High-Spin Single-Atom Sites for Sustained Oxygen Reduction.
The oxygen reduction reaction (ORR) is kinetically limited by spin-dependent adsorption of O2 and intermediates at catalytic sites, yet the high-spin configuration that promotes O2 activation is inherently metastable and suffers from uncontrolled spin evolution. Herein, we propose an electron-pumping strategy to overco...
