Tuning the performance of Mn/Beta in ozone catalytic oxidation of VOCs by variation of the Mn content and its localization in the zeolite structure.

[Display omitted] The performance of Mn/Beta in ozone catalytic oxidation (OZCO) of n -butane was optimized by variation of the Mn content (0.6–10 wt%) and localization of Mn species in the zeolite structure (as Mn2+ ions in the cationic position or MnO x species). It was found that localization of Mn2+ ions in the cationic positions of the zeolite favors high efficiency of ozone utilization in the OZCO process by minimizing O 3 consumption, while the formation of Mn oxide species improves the catalyst activity at a low temperature (50–70 °C), though at the expense of the ozone utilization efficiency.
