Abstract
En 中文
• FeS, Fe2P, and Fe3C nanoparticles were integrated with Fe-N-C single-atom sites on self-supported carbon nanofibers. • FeS/FeSA@CNF shows outstanding bifunctional oxygen electrocatalytic performance with high ORR activity and low OER over potential. • Synergy between FeS nanoparticles and Fe single atoms optimizes oxygen intermediate adsorption, enhancing bifunctional kinetics.
