Effect of preparation method on catalytic properties of Co-Mn-Al mixed oxides for N2O decomposition
Original language description
The present article is dealing with comprehensive analysis of the effect of preparation method performance of Co-Mn-Al mixed oxide catalyst on the N2O decomposition. Co-Mn-Al mixed oxides were prepared by three different methods: (i) from hydrotalcite-like precursors (Co-Mn-Al-HT-ex), (ii) by calcination of corresponding nitrates (Co-Mn-Al-nitr) and (iii) by mechanochemical reaction of Co, Mn, Al nitrates with NH4HCO3 (Co-Mn-Al-carb). The Co:Mn:Al molar ratio of 4:1:1 was kept constant in all catalysts.The catalysts were charakterization by AAS, XRD, Raman, FTIR, H2-TPR, TPD of CO2 and NH3 and tested for N2O decomposition in inert gas and simulated waste gas from HNO3 production. The highest catalytic activity was achieved on the calcined precursors having carbonates in their molecules (Co-Mn-Al-carb and Co-Mn-Al-HT-ex), the lowest one on the calcined Co-Mn-Al nitrates due to the lower surface area, less advantageous porous structure and worse reducibility.
