Mixed oxide Mg-Cu-Fe systems obtained form hydrotalcites were tested as catalysts for the selective catalytic oxidation (SCO) of ammonia to nitrogen and water vapor. Catalytic precursors were obtained by coprecipitation method. In the next step hydrotalkite-like materials were dried and calcined (600°C). Physico-chemical characterization of the samples included the following studies: structural analysis (XRD), textural measurements (BET) and redox experiments (TPR). Catalytic studies were performed in a fixed-bed flow reactor system. Analysis of reaction products was performed using QMS detector.
