Abstract
Abstract Fe−N−C catalysts with single‐atom Fe−N 4 configurations are highly needed owing to the high activity for oxygen reduction reaction (ORR). However, the limited intrinsic activity and dissatisfactory durability have significantly restrained the practical application of proton‐exchange membrane fuel cells (PEMFCs). Here, we demonstrate that constructing adjacent metal atomic clusters (ACs) is effective in boosting the ORR performance and stability of Fe−N 4 catalysts. The integration of Fe−N 4 configurations with highly uniform Co 4 ACs on the N‐doped carbon substrate (Co 4 @/Fe 1 @NC) is realized through a “pre‐constrained” strategy using Co 4 molecular clusters and Fe(acac) 3 implanted carbon…
