In article number 2006178, Baitao Li, Xiujun Wang, and co‐workers report a class of petal‐like Fe‐NC catalysts with an ultrathin porous nanosheet structure and proper hydrophilicity/hydrophobicity. This structure improves the exposure of inaccessible Fe‐N 4 active sites and enhances oxygen diffusion, ensuring fast mass transport for oxygen reduction reaction. This article presents a unique perspective on how to maximize the utilization of Fe‐N 4 active sites for electro‐catalytic reactions.
