摘要：
The catalytic decomposition of ozone on an alpha-Fe2O3 catalyst has been investigated within the temperature range 23-65-degrees-C. A high initial decomposition degree followed by a decrease is observed. It is found that the water vapor in the air-ozone mixture exercises almost no effect on the process. IR-spectroscopy has shown that the nitrogen oxides formed in the ozone generator are the main reason for the deactivation of the catalyst. A scheme of the deactivation process is proposed.
