The development of highly active and durable electrocatalysts for the oxygen evolution reaction (OER) is crucial for improving the overall efficiency of water splitting. Here, we reported a partial selenization strategy to fabricate iron doped nickel selenide nanosheets (Ni 0.85 Fe 0.15 Se@LDH/NF) featuring a heterostructure, using nickel foam (NF) supported NiFe-layered double hydroxide (NiFe-LDH) as a precursor, via a solvothermal reaction with selenium and sodium borohydride (NaBH 4 ). This study demonstrates that partial selenization strate...
