Ozone Decomposition over Alumina-Supported Copper, Manganese and Copper-Manganese Catalysts

I. Spasova, Penko Nikolov, Dimitar Mehandjiev

Abstract

Samples of three series alumina supported catalysts of copper, manganese and copper-manganese oxides are investigated with respect to ozone decomposition at low temperatures. The catalysts are found to be active in the reaction studied and the most active are mixed copper-manganese catalysts—they do not change their activity for prolonged time. The reason for the enhanced activity is suggested to be the presence of copper and manganese in various oxidation states.
