- Аннотация: In this study a comprehensive analysis of the influence of synthesis route of CuFe2O4 spinelmixed oxides on their catalytic performance in the N2O decomposition was carried out. A coprecipitationtechnique allowed one to obtain the CuFe2O4 spinel with a higher specific surfacearea and pore volume compared to the synthesis with the application of organic additives. Thisresulted in better catalytic performance of the CuFe2O4 samples prepared by co-precipitation. Themicrowave activation step with the duration of 1 min during the co-precipitation synthesis led tothe formation of the CuFe2O4 spinel with a higher content of oxygen vacancies per 1 m2 incomparison with the sample obtained without the microwave activation. This fact caused asignificantly higher specific activity of the CuFe2O4 spinel synthesized with the application of1 min microwave activation. The increase of the microwave treatment time led to the fast growthof the contents of the CuO and α-Fe2O3 phases, which are less active in the N2O decomposition,resulting in the activity drop.
