A titania-supported Mn oxide system made by incipient wetness impregnation method was investigated in the reaction of heterogeneous catalytic decomposition of ozone. The catalytic activity of the catalysts containing 6, 8 and 10 wt% manganese oxide was found using the decomposition coefficient γ which is proportional to ozone decomposition rate. It was established that all catalytic samples have activity towards ozone decomposition but most active was the catalyst possessing 10 wt% MnOx/TiO 2. The calculated values of γ were in the range 0.05×10 -4-0.4×10 -4. The experiments were performed in temperature range of 258 K to 313 K in a tube glass reactor. It was determined that the activation energy of the process is 11 kJ/mol.
