Abstract
Single-Atom Catalysts
In article number 2401187, Xifei Li and co-workers reveal the electron spin broken-symmetry of Fe-Co bimetallic single-atom catalysts, in which the strong charge polarization between Fe and Co sites, and the stray field produced by spin polarization at the Co site optimize the d-band center of the active atom, and effectively balance the adsorption-dissociation relationship of oxygen intermediates.
