Abstract
The composite material “ionite-sorbed ions” was obtained by ion exchange technology. The conditions for obtaining the composite material “ionite-sorbed ions” are studied. In the thermolysis of cationite with sorbed ions, the synthesis of complex oxide is carried out between ions located at atomic distances from each other. This facilitates and accelerates the formation of complex oxide. Thermolysis of carboxyl cationite KB-4P-2 with sorbed copper and manganese ions was performed at temperatures from 250-950°C . Control of the thermolysis mechanism of the composite material “ionite-sorbed ions” was carried out using thermograms. According to the scanning electron microscopy data, the obtained powder of complex copper and manganese oxide has a good crystallite structure. Data x-ray diffraction analysis confirmed the crystallization of a complex oxide of copper and manganese in orthorhombic crystal structure. A method for the synthesis of complex copper and manganese oxide powder based on the thermolysis process of the composite material “ionite-sorbed ions”, which has catalytic properties, has been developed.

One of the consequences of man-made impact on the environment is the intake of harmful substances, which worsens the state of atmospheric air
A method for obtaining fine powders of complex oxides based on Sol-gel technology using thermolysis of ionites with initially sorbed metal ions in a given ratio has been developed
To obtain the complex oxide, carboxyl cationite in ammonium form was taken and copper and manganese ions were sorbed in the ratio of 76% copper and 24% manganese
Summary
One of the consequences of man-made impact on the environment is the intake of harmful substances, which worsens the state of atmospheric air. Industrial enterprises and urban transport lead to an increase in the volume of harmful substances entering the atmosphere [1,2]. Much attention has been paid to the development of new catalytic systems for the removal of harmful exhaust gases from industrial plants and internal combustion engines of cars [3,4]. Numerous studies are being conducted to obtain catalysts that can purify gases from harmful compounds [5,6,7]. The combination of several metal oxides makes it possible to convert harmful polluting oxides into harmless ones in the exhaust gases
