Iron-group electrocatalysts for ambient nitrogen reduction reaction in aqueous media

Recent Advances in Nonprecious Metal Oxide Electrocatalysts and Photocatalysts for N2 Reduction Reaction under Ambient Condition

“…Electrocatalytic N 2 fixation is regarded as an auspicious and green means to achieve mild N 2 ‐to‐NH 3 conversion with adsorption, activation, and desorption processes. [ 26–29 ] The electrocatalytic NRR process encompasses the following elementary steps: 1) diffusion of N 2 into the surface; 2) activation of N 2 molecules to intermediates via the participation of protons and multiple electron transfer; and 3) desorption of the reduced product from the surface. In the concrete process, the water oxidation and N 2 reduction occur respectively in the anode and cathode three‐electrode system.…”

Rational design on photo(electro)catalysts for artificial nitrogen looping

“…1,45 So as to obtain superior NRR performance, the optimization of the electrocatalysts proves distinctly necessary. 46 In order to achieve a high activity and selectivity for electrocatalytic NRR, many types of advanced electrocatalysts have been investigated, including metals (eg, Fe, 47,48 Mo, 49,50 Cu, 51 Ru, 52,53 Rh, 54 Pd, 55 Au, [56][57][58] Pt, 59 etc), metal oxides (eg, TiO 2 , 60 69 VP, 70 etc), and so on.…”

Ammonia synthesis using Fe/BZY–RuO2 catalysts and a caesium dihydrogen phosphate-based electrolyte at intermediate temperatures

“…In the dissociative pathway, the NN triple bond is first cleaved to produce N*, while in the associative pathway, H first reacts with N 2 to produce NNH*. 6 If a Department of Chemical System Engineering, The University of Tokyo, 7-3-1, the N-N bond is retained during the addition of H, N 2 H 4 will be produced. As suggested by DFT calculation results, the associative mechanism is usually the most favourable pathway for the electrochemical synthesis of NH 3 .…”
