“…[104] Through density functional theory, some new materials have been predicted to be very suitable for NRR, such as B-terminated (111) polar surfaces of boron phosphide and boron arsenide, [105] single B-atom decorated BN edge (B@BN) [106] and the B-terminated zigzag edge. [107] However, boron-based NRR catalysts are rarely reported in research articles. Recently, Fan et al reported that several binding sites, especially those involving icosahedral boron in the 2D material, could catalyze N 2 reduction efficiently with strong ability of N 2 adsorption, thus benefiting initial activation.…”

Ammonia is an essential chemical for producing fertilizers and energy carriers. However, the industrial Haber-Bosch process causes huge CO 2 emissions and energy waste. As a promising alternative for Haber-Bosch process, electrochemical synthesis of ammonia has drawn much attention. Catalysts, as a vital part of electrochemical nitrogen reduction reaction (NRR), have developed rapidly in recent years. Compared to noble-metal catalysts, noble-metal-free catalysts possess a low-cost advantage. In this review, noble-metalfree catalysts, including metal-based materials, metal organic frameworks (MOFs), MXenes, and metal-free materials, are summarized. In addition, effective design strategies are discussed, along with the main problems and some potential directions of noble-metal-free NRR catalysts. 2. Advances in Noble-Metal-Free Catalysts for Electrocatalytic N 2 Reduction Recently, although noble metal catalysts have better catalytic performance in NRR, researchers have paid more attention to the utilization of resource-rich elements in the earth, including iron, molybdenum, carbon, nitrogen, boron and other nonnoble elements, in order to reduce costs and improve the [a

Ammonia is an important chemical and a potential carbon-free hydrogen-storage material. Currently, the industrial synthesis of ammonia is mainly achieved via the Haber-Bosch method, which requires high energy, temperatures, and pressures. An alternative method involves the electrocatalytic nitrogen reduction reaction (NRR), which uses an aqueous solution as a medium and requires mild reaction conditions. The key to the NRR is to select an appropriate catalyst to increase the ammonia yield and Faradic efficiency. With their diverse structures and easy regulation, carbon-based materials can provide abundant active sites for nitrogen absorption and excitation. Moreover, they are abundant, low cost, and readily available, making them promising for use in NRR applications. Accordingly, we review the latest progress in using carbonbased materials in the NRR, and the future development prospects of NRR catalysts are discussed. Finally, challenges and perspectives of the future research of NRR catalysts are provided.
