“…According to the analysis of in situ differential electrochemical mass spectrometry (DEMS), the reduction path of NO 3at CuBDC@Ti 3 C 2 T x is NO 3 -→ NO 2 -→ NO → NH 2 OH → NH 3 . In addition, Zhu et al synthesized the Materials of Institut Lavoisier (MIL)-101(Fe)@Nb 2 C heterostructure by a self-assembly strategy as an efficient NO 3 -RR electrocatalyst [63] . The introduction of MIL-101(Fe) gives Nb 2 C more electronic states near the Fermi level, which is conducive to improving the electrical conductivity.…”

“…MXene-based heterostructure catalysts typically have two or more distinct active components, which can increase NO 3 RR activity and inhibit competitive side reactions (HER) [58] . Benefiting from the synergistic effect between different components, the MXene-based heterostructure catalysts exhibit excellent FE (MIL-101(Fe)@Nb 2 C = 89.9%, BP/Nb 2 C = 90.4% and Bi 2 O 3 /Mxene = 91.1%) [63] , higher than that of MXenebased SAC (FeSA/Mxene = 82.9%) [75] . Due to the strong interaction between MXene and other component materials, MXene-based heterostructure catalysts showed better cyclic stability (BP/Nb 2 C = 15 cycles and Fe 1 Cu 2 @Mxene = 14 cycles) than MXene-based SACs (FeSA/Mxene = 5 cycles) [68] .…”

Ammonia (NH3) plays an irreplaceable role in traditional agriculture and emerging renewable energy. Its preparation in industry mainly relies on the energy-intensive Haber-Bosch process, which is associated with high energy consumption and large CO2 emissions. Recently, the nitrate reduction reaction (NO3-RR) driven by renewable energy has received extensive attention. This reaction can efficiently synthesize NH3 with water as a hydrogen source and NO3- as a nitrogen source under mild conditions, which is conducive to reducing energy consumption and promoting the carbon cycle. It is well known that the properties of electrocatalysts determine the performance of NO3-RR. As an emerging two-dimensional material, MXenes (transition metal carbides/nitrides/carbon nitrides) possess excellent electrical conductivity, large specific surface area and controllable surface functional groups, which shows great application potential in the field of NO3-RR. Herein, this review summarized the structure, properties and synthesis strategies of MXenes to elucidate the possibilities from foundation to application. Then, the latest research progress in applying MXene-based electrocatalysts to NO3-RR was summarized and the applicability of different NH3 detection methods was analyzed. Finally, the present challenges and future prospects of NO3-RR were presented. This review aimed to provide thoughtful insights into the rational design of MXene-based electrocatalysts for sustainable NH3 synthesis.

Metal–organic frameworks (MOFs) and covalent–organic frameworks (COFs)‐based aerogels are garnering significant attention owing to their unique chemical and structural properties. These materials harmoniously combine the advantages of MOFs and COFs—such as high surface area, customizable porosity, and varied chemical functionality—with the lightweight and structured porosity characteristic of aerogels. This combination opens up new avenues for advanced applications in fields where material efficiency and enhanced functionality are critical. This review provides a comparative overview of the synthetic strategies utilized to produce pristine MOF/COF aerogels as well as MOF/COF‐based hybrid aerogels, which are functionalized with molecular precursors and nanoscale materials. The versatility of these aerogels positions them as promising candidates for addressing complex challenges in environmental remediation, energy storage and conversion, sustainable water‐energy technologies, and chemical separations. Furthermore, this study discusses the current challenges and future prospects related to the synthesis techniques and applications of MOF/COF aerogels.

Exposing different facets on metal‐organic frameworks (MOFs) is highly desirable to enhance the performance for various applications, however, exploiting a concise and effective approach to achieve facet‐controlled synthesis of MOFs remains challenging. Here, by modulating the ratio of metal precursors to ligands, the facet‐engineered iron‐based MOFs (Fe‐MOFs) exhibits enhanced catalytic activity for Fenton reaction are explored, and the mechanism of facet‐dependent performance is revealed in detail. Fully exposed (101) and (100) facets on spindle‐shaped Fe‐MOFs enable rapid oxidation of colorless o‐phenylenediamine (OPD) to colored products, thereby establishing a dual‐mode platform for the detection of hydrogen peroxide (H2O2) and triacetone triperoxide (TATP). Thus, a detection limit as low as 2.06 nm is achieved, and robust selectivity against a wide range of common substances (>16 types) is obtained, which is further improved by incorporating a deep learning architecture with an SE‐VGG16 network model, enabling precise differentiation of oxidizing agents from captured images. The present strategy is expected will shine light on both the rational synthesis of nanomaterials with modulated morphologies and the exploitation of high‐performance trace chemical sensors.
