Concentration of VOC in air can be reduced applying total oxidation to carbon dioxide and water as final products. The catalysts containing noble metals are currently used, as they are highly active and stable but expensive. Oxides of transition metals are a cheaper alternative to the noble metal catalysts. For example, a mixture of Cu and Mn oxides was the first mixed oxide catalyst used for oxidation of VOC in submarines. Mixed oxides of transition metals can be easily obtained by calcination of layered double hydroxide (LDH) precursors. Optimization of the catalyst composition could also minimize undesirable reaction by products formed during VOC oxidation. Therefore, the effect of various combinations of divalent and trivalent transition metal cations in LDH precursors on properties of the related mixed oxide catalysts and their activity in ethanol deep oxidation is examined, with the aim to enhance the aktivity and selectivity of the mixed oxide catalysts.
