摘要：
Boron and nitrogen dual-doped carbon nanospheres (BNC-NSs) show exceptional electrocatalytic activity toward the nitrogen reduction reaction, with an NH<INF>3</INF> yield rate of 15.7 mu g<INF>NH<INF>3</INF></INF> h-1 mg<INF>cat.</INF>-1 and faradaic efficiency of 8.1% at -400 mV vs. RHE in 0.05 M H<INF>2</INF>SO<INF>4</INF> electrolyte. Meanwhile, stable electrocatalyst activity was also achieved for the BNC-NS electrocatalyst.
