Boron and nitrogen dual-doped carbon nanospheres for efficient electrochemical reduction of N2 to NH3

Abstract

Boron and nitrogen dual-doped carbon nanospheres (BNC-NSs) show exceptional electrocatalytic activity toward the nitrogen reduction reaction, with an NH₃ yield rate of 15.7 μg_NH3 h⁻¹ mg_cat.⁻¹ and faradaic efficiency of 8.1% at −400 mV vs. RHE in 0.05 M H₂SO₄ electrolyte. Meanwhile, stable electrocatalyst activity was also achieved for the BNC-NS electrocatalyst.
