摘要： 挥发性有机化合物（VOCs）及NOx是PM2.5和O3的重要前体物,其过量排放对环境质量及人类健康具有重要影响。与普通VOCs相比,含氮挥发性有机化合物（N-VOCs）由于氮杂原子的存在使得其环境控制策略更为复杂。因此,针对N-VOCs控制技术的开发及应用已成为当前的研究热点。为了实现N-VOCs催化氧化体系中低温高催化活性及高N2选择性两个关键目标,亟需设计高效、低成本的催化剂。本文系统总结了矿物材料、金属材料、单原子催化剂（SACs）、分子筛等在常见N-VOCs（N,N-二甲基甲酰胺、丙烯腈、乙腈、正丁胺、三乙胺等）催化氧化中的研究进展,介绍了N-VOCs的来源及危害;对胺类、腈类等典型N-VOCs催化氧化研究中的关键影响因素进行了归纳总结,主要包括催化活性、催化剂理化性质、催化构效关系及反应机理,提出了N-VOCs催化氧化过程中应避免中间产物深度氧化产生二次污染物;最后展望了N-VOCs催化氧化研究面临的前景和挑战,以期为未来N-VOCs的治理提供一定的理论指导与最新信息。

Abstract: Volatile organic compounds (VOCs) and NOx are important precursors of PM2.5 and O3, and their excessive emissions have significant impacts on environmental quality and human health. Compared with ordinary VOCs, nitrogen-containing volatile organic compounds (N-VOCs) have more complex environmental control strategies due to the presence of nitrogen heteroatoms. Therefore, the development and application of control technologies for N-VOCs have become a current research hotspot. In order to achieve the two key objectives of low-temperature high catalytic activity and high N2 selectivity in the catalytic oxidation system of N-VOCs, there is an urgent need to design efficient and low-cost catalysts. This paper systematically summarizes the research progress of mineral materials, metal materials, single atom catalysts (SACs) and molecular sieves in the catalytic oxidation of common N-VOCs (N,N-dimethylformamide, acrylonitrile, acetonitrile, n-butylamine, triethylamine, etc.), and describes the sources and hazards of N-VOCs The key factors affecting the catalytic oxidation of amines, nitriles and other typical N-VOCs are summarized, including catalytic activity, catalyst physicochemical properties, catalytic constitutive relationship and reaction mechanism, and it is proposed that secondary pollutants should be avoided from the deep oxidation of intermediate products in the process of catalytic oxidation of N-VOCs. Finally, the prospects and challenges of the research on catalytic oxidation of N-VOCs are discussed, aiming to provide certain theoretical guidance and the latest information for the treatment of N-VOCs in the future.
