Abstract:

Volatile organic compounds (VOCs) and nitrogen oxides (NO_x), recognized as pivotal precursors to PM_2.5 and O_3, necessitate the implementation of immediate and stringent reduction and control strategies. Nitrogen-containing volatile organic compounds (NVOCs), a quintessential class of heteroatom VOCs, profoundly impact atmospheric quality and public health. Oxidative control technologies targeting NVOCs require the synergistic reduction of NVOCs and the byproduct NO_x. Selective catalytic oxidation (SCO) has emerged as an effective technique for NVOC treatment, transforming waste gashydrocarbons into CO, and H,0, while selectively oxidizing nitrogen constituents to N,. The development of SC0 catalysts for NVOCs is critical, demanding catalysts with exceptional activity, selectivity, and durability. Current research on SCO catalysts focuses on noble metals such as platinum, palladium, silver, and transition metal oxides. This review examines advancements in noble metal and transition metal oxide catalysts for NVOC selective oxidation, outlines the strengths and limitations of various catalysts, and investigates the selective oxidation reaction mechanisms of NVOCs and their determinants on these catalysts. The aim is to provide insights for the innovation of high-performance catalysts designed for NVOC selective oxidation and to elucidate the reaction dynamics and mechanisms, ultimately advancing efficient NVOC control technologies and enhancing their effective purification and management.
