| description | Developing efficient and robust oxygen evolution reaction (OER) catalysts in seawater is important for green hydrogen generation but remains a significant challenge. Herein, we report a hierarchical core–shell OER electrocatalyst consisting of NiFe-layered double hydroxide nanosheets uniformly coated on a NiMoSx microcolumn supported on Ni foam (NiMoSx@NiFe-LDH/NF). Such NiMoSx@NiFe-LDH/NF shows excellent OER activity with a low overpotential of 297 mV to drive an industrial-level current density of 500 mA cm−2 in alkaline seawater and can operate continuously for 500 h without apparent activity degradation. In situ Raman spectroscopy studies indicate that the high-valent molybdate ions can promote the generation of disordered NiOOH active species and protect catalysts from Cl− corrosion during seawater oxidation. Additionally, the integrated alkaline seawater electrolyzer (with NiMoSx/NF as the cathode) is demonstrated to reach a current density of 100 mA cm−2 with a low voltage of 1.61 V, outperforming the benchmark Pt/C/NF||RuO2/NF. |
