Abstract:Triggering rapid reconstruction reactions holds the potential to approach the theoretical limits of the oxygen evolution reaction (OER), and spin state manipulation has shown great promise in this regard. In this study, the transition of Fe spin states from low to high was successfully achieved by adjusting the surface electronic structure of pentlandite. In‐situ characterization and kinetic simulations confirmed that the high‐spin state of Fe promoted the accumulation of OH− on the surface and accelerated ele… Show more
