摘要

在此，我们报告了首次通过超快焦耳加热合成的具有轴向氧配体的原子分散 Fe-N-C 催化剂（FeN4O/NC）。FeN4 和石墨烯之间形成的氧物种为 ORR 提供了高活性和稳定性。计算结果表明，FeN4O/NC 对含氧中间产物具有最佳的吸附-解吸作用，为设计高效的单原子电催化剂提供了一种可行的方法。

Axial oxygen-bridged FeN₄O/NC produced by ultrafast Joule heating for efficient oxygen reduction reaction.

Herein, we report an atomically dispersed Fe-N-C catalyst with axial oxygen ligands (FeN₄O/NC) synthesized for the first time by ultrafast Joule heating. The formation of oxygen species between FeN₄ and graphene offers high activity and stability for the ORR. The calculations indicate that FeN₄O/NC offers an optimal adsorption-desorption of oxygen-containing intermediates, providing a promising approach to designing efficient single-atom electrocatalysts.
