“…Many effective strategies have been devised to open up NRR electrocatalysts, including heteroatom doping, single-atom catalysts, defect engineering, heterostructural or dimensional manipulation, etc. , Most reported electrocatalysts typically involve various catalytic centers, which are hard to distinguish as their structures are not particularly clear and corresponding activities are relatively convoluted. There is scarce investigation on atomic resolution modulation of the catalyst structure.…”

The precise design and synthesis of active sites to improve catalyst's performance has emerged as a promising tactic for electrochemistry. However, it is challenging to combine different types of active sites and manipulate them simultaneously at atomic resolution. Here, we present a strategy to synthesize Re atom-doped Cu twin boundaries (TBs), through pulsed electrodeposition and boundary segregation. The Re-doped Cu TBs demonstrate a highly efficient nitrogen reduction reaction (NRR) performance. Re-doped Cu TBs showed a turnover frequency of ∼5889 s −1 , ∼800 times higher than the pure Cu TB active centers (∼7 s −1 ). In addition to the "acceptance−donation" activation of N 2 molecules, theoretical calculations also reveal that the Re−Re dimer on TB can boost the NRR and impede the hydrogen evolution reaction synchronously, rendering Re-doped Cu TB catalysts with high NRR activity and selectivity.

The development of earth‐abundant and non‐noble based metal catalysts for electrochemical nitrogen reduction towards sustainable ammonia production from N2 and H2O in the ambient atmosphere holds immense potential in realizing an alternate route to energy‐intensive Haber‐Bosch process. Herein, we have employed highly conductive MoO2 synthesized by hydrothermal route as an electrocatalyst for ammonia generation. The MoO2 catalyst was employed for electrochemical nitrogen reduction in N2 saturated 0.1 m HCl electrolyte in a two‐compartment cell. Ammonia yield rate of 2.30 μg h−1 mg−1cat and 2.40 % Faradaic efficiency has been obtained at a potential of −0.3 V vs. RHE. The MoO2 catalyst is selective for ammonia generation without any hydrazine formation. The metallic nature of MoO2 catalyst assists in achieving comparable activity for the electrochemical nitrogen reduction. The above catalyst has the potential for providing better ammonia yield rate by combining or doping with other active elements.

Ammonia (NH3) plays a significant role in the manufacture of fertilizers, nitrogen-containing chemical production, and hydrogen storage. The electrochemical nitrogen reduction reaction (e-NRR) is an attractive prospect for achieving clean and sustainable NH3 production, under mild conditions driven by renewable energy. The sluggish cleavage of N≡N bonds and poor selectivity of e-NRR are the primary challenges for e-NRR, over the competitive hydrogen evolution reaction (HER). The rational design of e-NRR electrocatalysts is of vital significance and should be based on a thorough understanding of the structure–activity relationship and mechanism. Among the various explored e-NRR catalysts, metal-based electrocatalysts have drawn increasing attention due to their remarkable performances. This review highlighted the recent progress and developments in metal-based electrocatalysts for e-NRR. Different kinds of metal-based electrocatalysts used in NH3 synthesis (including noble-metal-based catalysts, non-noble-metal-based catalysts, and metal compound catalysts) were introduced. The theoretical screening and the experimental practice of rational metal-based electrocatalyst design with different strategies were systematically summarized. Additionally, the structure–function relationship to improve the NH3 yield was evaluated. Finally, current challenges and perspectives of this burgeoning area were provided. The objective of this review is to provide a comprehensive understanding of metal-based e-NRR electrocatalysts with a focus on enhancing their efficiency in the future.
