"Thermal decomposition of prepared LDHs and formation of related mixed oxides were studied using high-temperature Xray powder diffraction and thermal analysis. A subsequent step is a complete decomposition of the layered structure to nanocrystalline spinel, the complete dehydration, and finally decarbonation of the mixed oxide phase. Spinel-type oxides were the primary crystallization products. Mg-containing primary spinels had practically empty tetrahedral cationic sites. A dramatic increase of the spinel cell size upon heating and analysis by Raman spectroscopy revealed a segregation of Co-rich spinel in Co-Mn and Co-Mn-Al specimens. These calcination products were tested as catalysts in the total oxidation of ethanol and decomposition of N2O." .
