Synergistic boron-dopants and boron-induced oxygen vacancies in MnO2 nanosheets to promote electrocatalytic nitrogen reduction

The synergistic effect of B-dopants and B-dopant-induced O-vacancies led to the significantly enhanced NRR activity of MnO₂ nanosheets with an NH₃ yield of 54.2 μg h⁻¹ mg⁻¹ (−0.4 V) and a faradaic efficiency of 16.8% (−0.2 V).
