The precise fabrication and regulation of the stable catalysts with desired performance still challengeable for single atom catalysts. Here, Ru atoms different coordination environment in Ni3FeN lattice are synthesized studied as a typical case over alkaline methanol electrooxidation. buried subsurface (Ni3FeN-Ruburied) exhibits high selectivity Faradaic efficiency to formate conversion. Meanwhile, operando spectroscopies reveal that Ni3FeN-Ruburied an optimized adsorption reactants along inhibited surface structural reconstruction. Additional theoretical simulations demonstrate displays regulated local electronic states metal reduced energy barrier potential determining step. This work not only reports high-efficient catalyst conversion condition, but also offers insight into rational design more accessible surficial active sites. Fine turning configuration substrate is challenging. authors report burying can stimulate sites thus promote overall catalytic
