Generalized Encapsulations of ZIF‐Based Fe–N–C Catalysts with Controllable Nitrogen‐Doped Carbon for Significantly‐Improved Stability Toward Oxygen Reduction Reaction (Small 25/2023)

Fe–N–C Catalysts In article number 2207671, Jia Li, Jianguo Liu, and co-workers develop a highly-catalytic Fe–N–C catalyst with a power density of >1 w cm−2 and prolonged lifetime (>40 h) using a controllable and efficient N–C coating strategy. The authors investigate the correlation between coating thickness and electrochemical performance. They also identify the stability improvement mechanism to the reduced carbon corrosion and iron loss in catalyst.
