Electrocatalytic water splitting for hydrogen production represents a crucial pathway toward establishing sustainable energy infrastructure and addressing environmental concerns, with the development of high-performance nonprecious metal catalysts being central focus. While Ni3S2 demonstrates potential as an electrocatalyst, its limited functionality suboptimal performance necessitate further enhancement. In this study, drawing inspiration from natural hydrogenases, we engineered novel NiFeSe/Ni3S2 composite electrocatalyst through integration NiFeSe Ni3S2. The synthesized catalyst displayed outstanding overall water-splitting in alkaline media, realizing current densities 100 10 mA cm-2 at remarkably low overpotentials 267.4 mV (vs RHE) oxygen evolution reaction (OER) 105.6 (HER), respectively. Remarkably, two-electrode electrolyzer incorporating achieved density 20 substantially reduced cell voltage 1.586 V. Comprehensive analysis revealed that strategic construction biomimetic active centers heterogeneous interfaces significantly modulates electronic structure, improved charge transfer, redistribution electron catalytic sites. This investigation provides valuable insights promising framework rational design bifunctional electrocatalysts applications.
