Abstract Transition metal selenides (TMSe) are promising oxygen evolution reaction (OER) electrocatalysts but act as precursors rather than the actual active phase, transforming into amorphous oxyhydroxides during OER. This transformation, along with formation of selenium oxyanions and unstable heterointerfaces, complicates structure‐activity relationship reduces stability. work introduces novel “layered‐hierarchical dual lattice strain engineering” to inhibit surface reconstruction Ni x Se by modulating both nickel foam (NF) substrate Mo 2 N nanosheets (NM) nanorods‐nanosheets catalytic layer (NiSe‐Ni 0.85 Se‐NiO, NSN) ultrafast interfacial bimetallic NiFeOOH coating, achieving optimized NM/NSN/NiFeOOH configuration. The NM induces strain, enhancing OER activity improving electron transport adhesion, while coating additional mitigating oxidative degradation, reinforcing structural integrity. catalyst demonstrates exceptional performance low overpotentials 208 mV@10 mA cm −2 outstanding stability over 100 h at in alkaline freshwater seawater. Theoretical analysis shows that effectively prevents degradation preserving sites for optimal intermediate interactions stabilizing electronic environment. provides a strategy TMSe beyond.
