| 英文摘要 | Atomically dispersed Fe-N-C electrocatalysts have displayed excellent catalytic performances towards the oxygen reduction reaction (ORR), while the identification of the genuine active sites remains a challenge. Herein, we report a Fe-N-C electrocatalyst of FeSA/HNPC featuring single-atomic FeN4 sites on hierarchically N-doped porous carbon (HNPC), which shows a very competitive ORR activity in alkaline solution even at a low electrocatalyst loading of 0.2 mg cm(-2) on the working electrode. A comparison of energy barriers in ORR reveals that the single-atomic FeN4 active sites in FeSA/HNPC existing in the form of pyrrole-N-4-Fe is more favorable than that of pyridine-N-4-Fe for the enhanced ORR activity. Understanding the nature of FeN4 active sites will greatly benefit the design of Fe-N-C electrocatalysts with highly effective ORR performances. |
