В настоящей работе исследовано каталитическое разложение озона на молекулярный кислород в каталитической смеси, содержащей оксиды марганца, меди и никеля. Реакцию изучали в присутствии термически модифицированных каталитических образцов, работающих при различных температурах и расходах озона. Изменения катализатора исследованы методом температурно программиируемого восстановления и ИК-спектроскопии. Фазовый состав катализатора из оксида металла был определен с помощью рентгеновской дифракции. Смесь катализаторов показала высокую активность при разложении озона на влажных и сухих смесях газов O3/O2. Был предложен механизм каталитического разложения озона.

The catalytic decomposition of ozone to molecular oxygen over catalytic mixture containing manganese, copper and nickel oxides was investigated in the present work. The reaction was studied in the presence of thermally modified catalytic samples operating at different temperatures and ozone flow rates. The catalyst changes were followed by temperature programmed reduction and IR-spectroscopy. The phase composition of the metal oxide catalyst was determined by X-ray diffraction. The catalyst mixture has shown high activity in ozone decomposition at wet and dry O3/O2 gas mixtures. The mechanism of catalytic ozone degradation was suggested.
