摘要：

Electrochemical N-2 reduction has emerged as a sustainable and eco-friendly route for the artificial synthesis of NH3 under ambient conditions, but active electrocatalysts are needed to drive the N-2 reduction reaction (NRR). Here, Bi nanodendrites are reported as an efficient NRR electrocatalyst for N-2 to NH3 conversion with excellent selectivity. In 0.1 M HCl, this catalyst achieves a large NH3 yield of 25.86 mu g h(-1) mg(cat.)(-1) and a high faradaic efficiency of 10.8% at -0.60 V and -0.55 V versus a reversible hydrogen electrode, respectively, with high electrochemical durability.
