For Ni2/CrBr3 and Ni8/CrBr3 catalysts, altering their AFM arrangement resulted in remarkable overpotential reduction for 2e -ORR, reaching 0.01 V respectively. The overpotential disparity between different AFM states was significant. Specifically, the overpotential for AFM1 and AFM2 magnetic states of Ni2/CrBr3 and Ni8/CrBr3 on 2e - ORR was 0.09 V and 0.25 V respectively, indicating precise regulation of catalyst ORR performance by adjusting magnetic state. In this vein, the pathway selective transformation of 4e -ORR and 2e -ORR is realized by regulating the presence of central
