Core–Shell IrPt Nanoalloy on La/Ni–Co3O4 for High-Performance Bifunctional PEM Electrolysis with Ultralow Noble Metal Loading

Core–Shell IrPt Nanoalloy on La/Ni–Co3O4 for High-Performance Bifunctional PEM Electrolysis with Ultralow Noble Metal Loading

Highlights Core–shell IrPt nanoalloy on La/Ni–Co₃O₄ achieves unprecedented bifunctional activity (2 A cm−2 at 1.72 V) in proton exchange membrane water electrolysis (PEMWE) with ultralow loadings (0.075 mg cm−2 Ir/Pt at both electrodes). 646-h durability in PEMWE cell (5 μV h−1 decay) via IrPt-core@...
