Abstract: The characteristics of Mn catalysts supported on different carriers (SiO2 and BEA zeolite) in the processes of ozone decomposition and ozone-catalytic oxidation (OZCO) of volatile organic compounds (VOCs) were studied using n-butane as an example. The parent SiO2 was inactive in the test reactions, and the characteristics of Mn/SiO2 were determined by the catalytic properties of the supported MnOx oxide. In contrast to SiO2, BEA zeolite demonstrated significant catalytic activity, although at a temperature 50°C higher than that for Mn/BEA. The data obtained allowed us to conclude that the catalytic characteristics of Mn/BEA at 30–100°C were also determined by the Mn component of the catalyst. At higher temperatures, the catalytic properties of BEA significantly affected the course of the OZCO process. The zeolite carrier improved hydrocarbon conversion at 100–200°C and decreased the amount of ozone required for the OZCO process over Mn/BEA.
