Abstract

Heteroatom doped atomically dispersed Fe<sub>1</sub> -NC catalysts have been found to show excellent activity toward oxygen reduction reaction (ORR). However, the origin of the enhanced activity is still controversial because the structure-function relationship governing the enhancement remains elus...
