Abstract: Environmentally friendly ammonia production is important for addressing the carbon emissions and substantial energy consumption that are currently associated with the chemical industry. In recent decades, many achievements are made in this area however, low production yield, poor selectivity, and unsatisfactory Faradaic efficiency hinder large‐scale applications. 2D, metal‐free electrocatalysts stand out from other candidates because of their physical, electronic, and chemical properties. In this study, recent developments of 2D‐based electrochemical materials for converting dinitrogen into ammonia in ambient conditions are systematically reviewed. First, recent unique progress and challenges on novel 2D electrocatalysts for the nitrogen reduction reaction are summarized. Then, various synthetic strategies for electrochemical materials and the influence of these methods have on the intrinsic material performance are highlighted. Last, by comparing current engineering strategies, electrochemical tests, and computational calculations, the opportunities, critical issues, and scientific challenges for 2D nanomaterials as stable, efficient catalysts, are analyzed. On the basis of this comparison, technology solutions are provided and rational principles for future studies are proposed.

Abstract: The room‐temperature nitrogen reduction reaction (NRR) is of paramount significance for both the fertilizer industry and fundamental catalysis science. To produce ammonia from water, air, and sunlight, the photocatalytic NRR is targeted to significantly release the energy and environmental pressure associated with the current Habor–Bosch process. In this context, herein, the knowledge‐driven design of boron‐doped TiO 2 is demonstrated as a photocatalyst for the nitrogen reduction reaction. Among 54 catalysts in the reported library, anatase TiO 2 (101) modified by boron doping is identified as an exceptional NRR catalyst with strong visible‐light absorption (bandgap 1.92 eV) and excellent reactivity with a small thermodynamic barrier (0.44 eV) as well as a high turnover frequency (1.08 × 10 −5 s −1 site −1 ). Experimentally, the predictions of this work are validated using a B‐doped TiO 2 nanosheet, achieving ammonia production with a yield of 3.35 mg h −1 g −1 under simulated sunlight irradiation, which significantly renews the performance record for Ti‐based photocatalyst for the NRR. This work highlights the importance of dual active site catalysts for nitrogen activation and reduction and demonstrates the capacity of knowledge‐driven catalyst design.
