Abstract The abundant seawater resources provide favorable advantages for the large‐scale application of electrolysis to produce hydrogen. However, catalysts are prone triggering chlorine evolution reaction (CER) and easily corroded by Cl − , which key challenges that need urgent resolution in technology. Here, a crystal/amorphous heterostructure bifunctional composite catalyst (caMo‐NiFePO/NMF) splitting is synthesized through situ etching phosphorylation. incorporation Mo facilitates formation crystalline‐amorphous interfaces adjusts Fe electronic states d‐band centers, thereby boosting adsorption capacity * OOH intermediates repulsion forming dynamic OOH‐rich, ‐poor Janus interface. This enhances catalytic activity prevents deep reconstruction toward hydroxyl metal oxide, leading highly stable effective splitting. Noteworthy, caMo‐NiFePO/NMF requires low overpotential 328 mV reach 500 mA cm −2 alkaline oxygen (OER), avoiding CER. It also shows excellent with 327 hydrogen (HER). As catalyst, demonstrates performance cell potential 1.7 V achieve 100 seawater, maintaining remarkable stability over 1000 h.
