Abstract
Long-range ordered high-entropy intermetallics (HEIs) were synthesized via a thermodynamically-driven atomic ordering strategy. The (FeCoNi)(RuPt) HEI achieves 200 mA cm−2 at an overpotential of 56 mV and a remarkable low Tafel slope of 50.4 mV dec−1 in alkaline seawater. In situ Raman spectroscopy reveals the presence of Co–OH, M–OH–M, and Pt–OH–Pt adsorption sites on the (FeCoNi)(RuPt) surface, which are crucial for water dissociation.
