摘要

采用热力学驱动原子有序策略合成了长程有序高熵金属间化合物。在碱性海水中，（FeCoNi）（corrupt） HEI在过电位为56 mV时达到200 mA cm-2， Tafel斜率为50.1 mV dec1。原位拉曼光谱显示（FeCoNi）（corruption）表面存在Co-OH， M-OH-M和Pt-OH-Pt吸附位点，这是水解离的关键。

Long-range ordered high-entropy intermetallics enable stable and efficient hydrogen evolution in seawater

Long-range ordered high-entropy intermetallics (HEIs) was synthesized via a thermodynamically-driven atomic ordering strategy. The (FeCoNi)(RuPt) HEI achieves 200 mA cm-2 at overpotential of 56 mV and a remarkable low Tafel slope of 50.1 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.
