Abstract
In order to elucidate the previously-reported critical dependence of alcohol synthesis activity of Ir-Mo-Na 2O/Al 2O 3 catalysts upon the thermal-decomposition temperature of the precursor salts, thermal-decomposition behaviors of IrCl 4, (NH 4) 6Mo 7O 24 and NaNO 3, and of their mixtures, both supported on alumina, were examined. When three precursor salts were impregnated simultaneously on alumina, they decomposed by three different processes: the first was observed at 180°C and was attributed to the Ir-catalyzed decomposition of NH 4NO 3 formed by double-decomposition between NaNO 3 and (NH 4) 6Mo 7O 24. The second was observed at around 250°C and was concluded to be due to the double-decomposition between NaNO 3 and “Ir 2OCl 6” formed by partial decomposition of IrCl 4 at the impregnation stage. The last (450°C) was attributed to the decomposition of the remaining “Ir 2OCl 6”.
