The mixed oxides obtained by calcination at 500 \u00B0C were characterized using various techniques (XRD, XPS, IR and Raman spectroscopy, BET surface area measurements, TPD and TPR). The activities of calcined hydrotalcites were tested for N2O decomposition in an inert gas, and in the presence of oxygen and water vapor as well. Among the catalysts screened, the catalyst prepared from Co hydrotalcite containing Al and Mn as the trivalent cation showed the highest activity. Redox properties of the catalysts play an important role in the reaction and optimum extent of reduction is necessary for achievement of the highest catalytic activity. Based on the obtained results a redox model of N2O decomposition was proposed. At N2O and O2 concentrations typical for waste gases, N2O decomposition is well described by the 1st rate law." .
