Unraveling the Origin of Sulfur-Doped Fe-N-C Single-Atom Catalyst for Enhanced Oxygen Reduction Activity: Effect of Iron Spin-State Tuning

Zhaoyang Chen et al.

Summary: In this study, sulfur-doped Fe-1-NC catalyst was found to exhibit superior activity towards ORR compared to traditional Fe-NC materials. The incorporation of sulfur in the second coordination sphere of Fe-1-NC was shown to induce a transition of spin polarization configuration, with the low spin single-Fe3+-atom identified as the active site for ORR through operando Fe-57 Mossbauer spectra. Additionally, DFT calculations revealed that the lower spin state of the Fe center after sulfur doping promotes the OH* desorption process.
