Abstract

Abstract : High-index {331} faceted Au great stellated dodecahedra are synthesized by a double-step potential method in an ageing HAuCl4 /DES solution, which exhibit excellent electrocatalytic activity for the nitrogen reduction reaction. 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.
