Abstract

Carbon monoxide hydrogenation activity over TiO2-or SiO2-supported Fe—Co—Ni alloy decreased with addition of Cr, Mo, or Mn due to suppressed adsorption of hydrogen and carbon monoxide on the alloy surface. However the selectivity to oxygenated compounds such as ethanol or acetone was enhanced over Cr-and Mo-added Fe—Co—Ni alloy. On the other hand, the chain growth probability was promoted over Mn added 50 Co 50 Ni. Since the vibrational frequency of adsorbed NO shifted to higher wavenumbers, the electron density of Fe—Co—Ni alloy seems to be lowered by the addition of Cr, Mo, and Mn. Dissociative chemisorption of CO is suppressed on electron deficient surface of the Fe—Co—Ni alloy, resulting in high selectivity to oxygenated compounds.
