The spin-dependent transition between triplet O₂ and singlet Li₂O₂ is studied on a fully-exposed PtFe cluster catalyst. The fast spin-conserved electron transfer enabled by the directional e-spins at Fe−Fe sites, markedly accelerates the kinetics of O₂/Li₂O₂ redox reaction. This work provides new insights into enhancing the cathodic kinetics of Li-O₂ battery through spintronic electrocatalysis and constructing spin catalysts at atomic level.

完全暴露的 PtFe 簇中的自旋选择性通道可实现 Li-O2 电池的快速阴极动力学

在完全暴露的 PtFe 团簇催化剂上研究了三重态 O₂ 和单重态 Li₂O₂ 之间的自旋依赖性转变。Fe-Fe 位点的定向 e-spin 实现的快速自旋守恒电子转移显着加速了 O₂/Li₂O₂ 氧化还原反应的动力学。这项工作为通过自旋电子电催化增强_{Li-O 2} 电池的阴极动力学和在原子水平构建自旋催化剂提供了新的见解。
