Promoting electrocatalytic nitrogen reduction to ammonia via Fe-boosted nitrogen activation on MnO2 surfaces

Fe-doped MnO2 shows excellent NRR behaviour including a high faradaic efficiency of 16.8%, a high NH3 formation rate of 39.2 μg h−1 mgcat.−1 at −0.29 V vs. the reversible hydrogen electrode in 0.1 M Na2SO4, and good stability.
