Au great stellated dodecahedra (GSD), one of the Kepler-Poinsot solids, are synthesized by an electrochemical double-step potential method in a choline chloride-urea based deep eutectic solvent. The as-synthesized Au GSD are bound by high-index {331} facets and exhibit excellent electrocatalytic performance for the nitrogen reduction reaction with a high NH3 yield rate (49.96 μg h-1 cm-2) and faradaic efficiency (28.59%) under ambient conditions.
通过基于氯化胆碱-尿素的深共熔溶剂中的电化学双步电位法合成了二十面体金星（GSD），它是开普勒-波因索特多面体之一。所合成的金GSD由高指数{331}晶面所包围，并且在环境条件下对氮还原反应表现出优异的电催化性能，具有高的NH3产率（49.96 μg h-1 cm-2）和法拉第效率（28.59%）。
