The oxygen electrocatalysis on iron-nitrogen-carbon (Fe−N−C) catalysts is highly correlated to the spin configuration of Fe active sites. A crystal field and magnetic field synergetic strategy is proposed to regulate spin state of Fe−N−C from low spin (LS) to intermediate spin (MS) and high spin (HS), and the high spin Fe^III−N−C is the most favorable for oxygen electrocatalysis.

晶体场和磁场调节原子铁自旋态以增强可充电锌空气电池中的氧电催化

铁-氮-碳（Fe−N−C）催化剂上的氧电催化与Fe活性位点的自旋构型高度相关。提出了晶体场和磁场协同策略来调节 Fe−N−C 的自旋态从低自旋（LS）到中自旋（MS）和高自旋（HS），高自旋 Fe III −N− ^C为最有利于氧电催化。
