Abstract: Volatile organic compounds (VOCs) and NO_x are important precursors of PM_2.5 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.
