摘要：Rh/TiO2, Rh-Fe/TiO2 and Rh-Fe-Ce/TiO2 catalysts were prepared by the incipient wetness impregnation method for ethanol synthesis from syngas and investigated by XRD, N-2 adsorption-desorption, XPS, CO-TPD and DRIFTS techniques. The results indicated that the incorporation of Ce to Rh-Fe/TiO2 effectively coordinated the appropriate proportion of linear, gem-dicarbonyl and bridged CO species, leading to a balance between CO dissociation and CO insertion, which resulted in enhancing the CO conversion and ethanol selectivity.
