Edge-Site Engineering of Atomically Dispersed Fe–N4 by Selective C–N Bond Cleavage for Enhanced Oxygen Reduction Reaction Activities

Single-atom metal–nitrogen–carbon (M–N–C) catalysts have sparked intense interests, but the catalytic contribution of N-bonding environment neighboring M–N4 sites lacks attention. Herein, a series of Fe–N–C nanoarchitectures have been prepared, which confer adjustable numbers of atomically dispersed... View More
