Alkali Metals as Promoters in Co-Mn-Al Mixed Oxide for N2O Decomposition

Popis výsledku v původním jazyce

The Co-Mn-Al mixed oxide catalysts over Al2O3/Al supports were obtained by calcination of layered double hydroxide (LDH) precursors formed on anodized aluminum foils during hydrothermal reaction in aqueous solutions containing Co and Mn nitrates. The precursors crystallized as thin curved platelets with nearly perpendicular orientation to the support. The Mn/Co molar ratio in the range from about 4 to 8 in the nitrate solution was found to be favorable for obtaining catalysts with demanded contents of active components. The specific activity of the catalysts increased with increasing Mn/Co molar ratio in the solid up to value of about 0.4. Compared to the grained catalyst, the layers of Co-Mn-Al mixed oxides formed over anodized aluminum foils showed slightly higher specific activity in the total oxidation of ethanol. Formation of main reaction intermediate, acetaldehyde did not change practically with increasing Mn/Co molar ratio.
