“…In addition to N, the effects of other dopants, such as S, 20,24 B, 101 and dual‐element dopants, such as B‐N 28 and N‐P 29 , on the production rate have also been discussed. However, the understanding of the configurations for the active moieties in these heteroatom‐doped carbon catalysts is still not enough.…”

Ammonia is not only an important platform chemical for industrial and agricultural use but is also a novel energy‐carrying molecule. The electrochemical reduction method for ambient ammonia synthesis is emerging as a promising strategy for the replacement of the current Haber–Bosch ammonia synthesis method, which consumes a large amount of energy and natural gas (hydrogen resource) while releasing substantial greenhouse gases (eg, carbon dioxide). The challenges in electrochemical ammonia synthesis, also known as nitrogen reduction reaction, primarily include the cleavage of extremely stable N≡N bonds and the competitive hydrogen evolution reaction in routine aqueous media, which significantly leads to a low production rate and Faradaic efficiency. The rational design and engineering of the electrocatalyst/electrolyte interface are crucial to address these challenges. Herein, recent achievements for catalyst/electrolyte interface engineering are reviewed to provide insights into enhancing the production rate and Faradaic efficiency. Perspectives on future research and development of the electrochemical ammonia synthesis from theory to practice will be provided.

“…The introduction of defects into electrocatalysts can effectively enhance the catalytic performance. [67][68][69] In terms of graphene, its defects can be divided into two categories: extrinsic defects (heteroatoms) and intrinsic defects (edge, vacancy, and dislocation defects). [70] Up to now, several works have shown that the introduction of intrinsic defects onto graphene can effectively enhance the NRR performance.…”

Ammonia (NH3) plays a key role in human society. The conventional Haber–Bosch process under high temperature and pressure is widely used to synthesize NH3, resulting in huge energy costs and serious environmental issues. At present, the electrochemical conversion of nitrogen (N2) and water (H2O) into NH3 at ambient conditions is considered as a promising and alternative method, and electrocatalysts are critical for nitrogen reduction reaction (NRR) to realize NH3 synthesis. Graphene as an emerging 2D material has received significant attention in electrocatalysis NRR due to its unique properties such as high conductivity, specific surface area, a distinct 2D structure, and simplicity for modification. Herein, the electrochemical basis for NRR is provided including reactions in the NRR system, NRR mechanisms, criteria for NRR electrocatalysts (density functional theory and experiments), and verifying the nitrogen source and electrolytes. Then, the effect of doping (nonmetallic elements and single/dual metal atoms) and intrinsic defects on the NRR performance for graphene derivatives is reviewed, and the graphene composite electrocatalysts for NRR are summarized. Furthermore, deep sights and existing issues toward the further development of graphene derivatives and graphene composite electrocatalysts on NRR are discussed.

“…The excellent physical, electronic, and chemical properties of two-dimensional (2D) materials have attracted extensive scientific research [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ]. In addition, 2D materials, such as molybdenum disulfide, graphene, and metal–organic frameworks (MOFs) [ 14 , 15 , 16 ], have emerged as potential candidates for electrochemical nitrogen reduction reactions (NRRs). Notably, MXene, a new member of the 2D material family that joined in 2011 [ 17 ], has developed rapidly in the past nine years [ 17 , 18 , 19 ].…”

The possibility of using transition metal (TM)/MXene as a catalyst for the nitrogen reduction reaction (NRR) was studied by density functional theory, in which TM is an Fe atom, and MXene is pure Ti3C2O2 or Ti3C2O2−x doped with N/F/P/S/Cl. The adsorption energy and Gibbs free energy were calculated to describe the limiting potentials of N2 activation and reduction, respectively. N2 activation was spontaneous, and the reduction potential-limiting step may be the hydrogenation of N2 to *NNH and the desorption of *NH3 to NH3. The charge transfer of the adsorbed Fe atoms to N2 molecules weakened the interaction of N≡N, which indicates that Fe/MXene is a potential catalytic material for the NRR. In particular, doping with nonmetals F and S reduced the limiting potential of the two potential-limiting steps in the reduction reaction, compared with the undoped pure structure. Thus, Fe/MXenes doped with these nonmetals are the best candidates among these structures.
