Catalytic Decomposition of Residual Ozone over Cactus-like MnO2 Nanosphere: Synergistic Mechanism and SO2/H2O Interference

Hairong Tang et al.

Summary: This study investigated the application of four manganese oxides with different crystal structures in an ozone synergistic-oxidation system. Among them, a cactus-like MnO2-IV nanosphere exhibited the highest ozone decomposition activity and showed good tolerance to water vapor and SO2/H2O. The interference mechanism of O-2/O-3/H2O/SO2 molecules on MnO2-IV was revealed.

Promotional effects of ruthenium oxide on catalytic oxidation of dichloromethane over the tungsten-titanium binary oxides catalyst

Chenghang Zheng et al.

Summary: Catalytic oxidation with TiO2 doped with niobium and tungsten showed high activity in removing dichloromethane, but experienced deactivation due to the reaction between tungsten and chlorine. Loading RuO2 helped prevent this deactivation, improving resistance to Cl-poisoning and stability of the catalysts.

Interplay effect on simultaneous catalytic oxidation of NOx and toluene over different crystal types of MnO2 catalysts

Jiaming Shao et al.

Summary: This study investigated the simultaneous catalytic oxidation of NO and toluene, finding that toluene inhibited NO conversion while NO also elevated toluene conversion temperature. During simultaneous oxidation, NO oxidation efficiency increased as toluene degraded, providing a feasible method for removing NO and VOCs simultaneously.

How to achieve complete elimination of Cl-VOCs: A critical review on byproducts formation and inhibition strategies during catalytic oxidation

Fawei Lin et al.

Summary: This review examines the formation of byproducts in the catalytic oxidation of Cl-VOCs, with a focus on the potential risks posed by polychlorinated byproducts. Strategies to inhibit byproducts formation are explored, with an emphasis on the need to develop catalysts for the efficient and complete elimination of Cl-VOCs. Further research is needed to understand the migration and evolution routes of Cl species and design catalysts to achieve truly complete elimination of Cl-VOCs without secondary pollution.

Chlorine-Resistant Hollow Nanosphere-Like VOx/CeO2 Catalysts for Highly Selective and Stable Destruction of 1,2-Dichloroethane: Byproduct Inhibition and Reaction Mechanism

Yu Huang et al.

Summary: The research focused on developing economical and robust catalysts for the destruction of chlorinated volatile organic compounds (CVOCs). The hollow nanosphere-like VOx/CeO2 catalysts, particularly the V0.05Ce catalyst, showed superior catalytic activity and selectivity due to the presence of oxygen vacancies and excellent low-temperature redox ability. Moreover, the presence of water vapor facilitated the activation and deep destruction of 1,2-DCE over V0.05Ce catalyst by efficiently removing Cl species from the surface.

Catalytic oxidation of chlorinated volatile organic compounds over Mn-Ti composite oxides catalysts: Elucidating the influence of surface acidity

Hao Liu et al.

Summary: The reducibility and surface acidity of Mn-Ti composite oxides were controlled by adjusting the Mn/Ti molar ratio, impacting their catalytic activity for the deep oxidation of vinyl chloride. It was found that the catalyst surface acidity played a decisive role in the oxidation process, while Lewis acidic sites from Ti species also influenced the catalytic activity.
