O2‐Accessible Fe–N4 Active Site Density Boosts Efficient Oxygen Reduction to Fuel‐Cell Level
Advanced Materials, EarlyView.This study investigates the role of hierarchical nanostructure design in optimizing oxygen mass transport for the oxygen reduction. Using atomically dispersed Fe–N–C catalysts with solid, yolk‐shell, and hollow structures, it demonstrates that the yolk‐shell architecture provides superior O2 accessibility to active Fe–N4 sites.

Advanced Materials, EarlyView.The novel gradient‐modified LRMO has been synthesized via a one‐step mechano‐fusion process, with simultaneous S and Zr co‐doping in the near‐surface region and an amorphous coating. The synergistic co‐functionalization stabilizes the oxygen framework, enhances charge transport, and suppresses oxygen dimerization under high potential, which enable ...
