The catalytic performance of single-atom catalysts (SACs) is strongly related with the spatial distribution of reactive site and their spin electronic configuration. However, the spin-related hydrogen evolution reaction governed by super-exchange interaction among individual and interacting sites still need to be understood. Herein, we suggest a dual-metal-hybridized strategy to rearrange spin electron occupation through regulating inter-site distances, in which the strong super-exchange interaction from adjacent Mn–N4moieties can effectively alter the electronic structure of original Fe–N4for an appropriate inter-site distance of 8.65 Å. Different from intrinsic interaction between two neighboring Fe–N4SACs, this asymmetric super-exchange interaction makes the HER activity is enhanced obviously. This work provides a new insight into regulating spin-related orbital interaction and catalytic activity.
