This paper synthesized bimetallic MnCoO_x catalysts for efficient synergistic ozonation of chlorobenzene (CB) and NO with presence of complicated components in flue gas. MnCoO_x-I (MnCo-I) with 3D sphere-like morphology and crystalline structure of MnCo₂O_4.5 attained CB conversion of 90% with the O₃/CB of 10.0 at 120 ^oC. High porosity, CO₂ desorption ability and abundant acidity contributed to its excellent performance. Catalytic co-ozonation of CB/NO over MnCo-I demonstrated that NO presence possessed negligible effects for CB conversion. But promoted mineralization rate increase, which originate from the high valence intermediates of NO ozonation. Besides, SO₂ and 1,2-dichloroethane (DCE) introduction promoted CB ozonation and CB/NO co-ozonation, while H₂O, and benzene (PhH) presence demonstrated opposite but not obvious tendency. The chlorinated methane species were dramatically increased with DCE presence, while the chlorinated benzene was promoted by NO addition. These observations provided a significant brand-new insight for VOC catalytic ozonation under practical conditions.

本文合成了双金属MnCoO _x催化剂，用于烟气中存在复杂组分的氯苯（CB）和NO的高效协同臭氧化。具有 3D 球形形态和 MnCo ₂ O _4.5晶体结构的MnCoO _x -I (MnCo-I)在 120 ^o C 下实现了 90% 的 CB 转化率，O ₃ /CB 为 10.0 。高孔隙率，CO ₂解吸能力和丰富的酸度促成了其优异的性能。CB/NO 在 MnCo-I 上的催化共臭氧化表明 NO 的存在对 CB 转化的影响可以忽略不计。但促进了矿化率的增加，这源于NO臭氧化的高价中间体。此外，SO ₂和1,2-二氯乙烷(DCE) 的引入促进了CB 臭氧化和CB/NO 共臭氧化，而H ₂ O 和苯(PhH) 的存在则表现出相反但不明显的趋势。DCE 的存在显着增加了氯化甲烷物种，而 NO 添加促进了氯化苯。这些观察结果为实际条件下VOC催化臭氧化提供了重要的全新见解。
