A novel process for S-VOCs degradation using wet scrubbing coupled with catalytic ozonation was developed for first time. We report redox-robust catalysts consisting of Ag(0)/Ag(I) species decorated rambutan-like MnO₂ hollow microspheres (Ag/R-MnO₂) with strong metal-metal oxide interaction (MMOI) exhibited superior catalytic ozonation performance for CH₃SH elimination. The optimum Ag/R-MnO₂ reached a significant improvement in CH₃SH elimination of 96.9% conversion over pristine R-MnO₂ under GHSV of 75,000 mL h⁻¹ g⁻¹, and O₃ utilization rate of 92.3%. An outstanding stability of Ag/R-MnO₂ under wet catalytic ozonation process was demonstrated, which outperformed that in gaseous system. CH₃SH was captured by aqueous solution and preferentially chemisorbed on Ag, then deeply oxidized to the final products of SO₄^2-/CO₃^2- via catalytic ozonation by multivalent R-MnO₂. The excellent performance can be ascribed to efficient electron replenishing interaction between Ag(0)/Ag(I) and multivalent R-MnO_2, efficient O₃ activation through oxygen vacancies-rich R-MnO₂, and enhanced mass diffusion in wet scrubbing process.

首次开发了一种使用湿法洗涤结合催化臭氧化降解 S-VOC 的新工艺。我们报告了由 Ag(0)/Ag(I) 物种装饰的红毛丹状 MnO ₂空心微球 (Ag/R-MnO ₂ )组成的氧化还原稳健催化剂，具有强金属-金属氧化物相互作用 (MMOI)，表现出优异的催化臭氧化性能。 CH ₃ SH消除。在75,000 mL h ^-1 g ^{-1 的}GHSV和92.3%的O ₃利用率下，最佳的Ag/R-MnO ₂在CH ₃ SH消除方面达到了比原始R-MnO ₂ 96.9%的转化率的显着改进。Ag/R-MnO ₂的出色稳定性展示了湿法催化臭氧化过程，其性能优于气态系统。CH ₃ SH 被水溶液捕获并优先化学吸附在Ag 上，然后通过多价R-MnO ₂催化臭氧化将其深度氧化为SO ₄ ^2- /CO ₃ ^2-最终产物。优异的性能可归因于 Ag(0)/Ag(I) 和多价 R-MnO ₂之间有效的电子补充相互作用_，通过富含氧空位的 R-MnO ₂有效激活O ₃，以及在湿法洗涤过程中增强的质量扩散.
