NH₃, essential for producing artificial fertilizers and several military and commercial products, is being produced at a large scale to satisfy increasing demands. The inevitable leakage of NH₃ during its utilization, even in trace concentrations, poses significant environmental and health risks because of its highly toxic and reactive nature. Although numerous techniques have been developed for the removal of atmospheric NH₃, conventional NH₃ abatement systems possess the disadvantages of high maintenance cost, low selectivity, and emission of secondary wastes. In this context, highly tunable porous materials such as metal–organic frameworks, covalent organic frameworks, hydrogen organic frameworks, porous organic polymers, and their composite materials have emerged as next‐generation NH₃ adsorbents. Herein, recent progress in the development of porous NH₃ adsorbents is summarized; furthermore, factors affecting NH₃ capture are analyzed to provide a reasonable strategy for the design and synthesis of promising materials for NH₃ abatement.

用于去除 NH3 气体的新兴多孔材料及其复合材料

NH ₃对于生产人造肥料和多种军用和商业产品至关重要，目前正在大规模生产以满足不断增长的需求。_{NH 3}在使用过程中不可避免地会泄漏，即使是痕量浓度，由于其高毒性和反应性，也会造成重大的环境和健康风险。尽管已经开发了许多技术来去除大气中的NH ₃，但是传统的NH ₃减排系统具有维护成本高、选择性低和产生二次废物的缺点。在这种背景下，高度可调的多孔材料，如金属有机骨架、共价有机骨架、氢有机骨架、多孔有机聚合物及其复合材料已成为下一代NH ₃吸附剂。本文综述了多孔NH ₃吸附剂的最新进展；此外，还分析了影响NH _{3捕获的因素，为设计和合成有前景的NH 3}减排材料提供合理的策略。
