-
Precisely located S doping of atomic Fe-N4 in Fe(N3)(N–C–S) motif was realized.
-
This S doping renders weakened *OH binding and faster charge transfer on Fe-N4.
-
Fe-NSC showed excellent oxygen reduction reaction performance with onset potential ~ 1.09 V and half-wave potential ~ 0.92 V.

原子分散的Fe-N 4修饰的S精确定位，可高效还原氧气
-
实现了在Fe（N 3）（NC–S）母题中精确定位的Fe-N 4原子的S掺杂。
-
该S掺杂使得弱的* OH结合和在Fe-N 4上的电荷转移更快。
-
Fe-NSC表现出优异的氧还原反应性能，起始电势约为1.09 V，半波电势约为0.92 V.
