| 英文摘要 | Adjusting the electronic structure of the active center is a highly effective strategy for improving the performance of catalysts. Herein, we report an atomically dispersed catalyst (FeCl1N4/CNS), which realized for the first time a great improvement of the ORR by controlling the electronic structure of the central metal with a coordinated chlorine. The half-wave potential of FeCl1N4/CNS is E-1/2 = 0.921 V, which is the highest among the reported values for non-precious metal electrocatalysts and far exceeds that of FeN4/CN and commercial Pt/C in alkaline solution. Besides an exceptionally high kinetic current density (J(k)) of 41.11 mA cm(-2) at 0.85 V, it also has a good methanol tolerance and outstanding stability. Experiments and DFT demonstrated that the near-range interaction with chlorine and the long-range interaction with sulfur of Fe modulated the electronic structure of the active site, thus resulting in a great improvement of the ORR in alkaline media. The present findings could open new avenues for the design of superior electrocatalysts. |
