In situ-derived boron-doped graphene quantum dots can significantly improve the activity of boron carbide nanosheets for artificial N2 fixation and reduction with superior electrocatalytic activity (NH3 yield: 28.6 μg h-1 mgcat.-1 at -0.45 V vs. RHE; faradaic efficiency: 16.7%), high electrochemical stability, and high selectivity in 0.1 M HCl under ambient conditions.
