An Ion‐Imprinting Derived Strategy to Synthesize Single‐Atom Iron Electrocatalysts for Oxygen Reduction

Carbon‐based single‐atom catalysts (CSACs) have recently received extensive attention in catalysis research. However, the preparation process of CSACs involves a high‐temperature treatment, during which metal atoms are mobile and aggregated into nanoparticles, detrimental to the catalytic performance. Herein, an ion‐imprinting derived strategy is proposed to synthesize CSACs, in which isolated metal–nitrogen–carbon (Me–N 4 –C x ) moiety...
