Abstract

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.
