Abstract: The structures of oxidic and sulfided Rh-Mo-K/AC catalysts were studied by means of XRD and EXAFS techniques. Activities for mixed alcohol synthesis via CO hydrogenation were used to measure the catalytic properties of these catalysts. In the oxidic Rh-Mo-K/AC catalyst samples, there is strong interaction between Rh and Mo species, which may shift K2Mo2O7to MoO2. Molybdenum species are mainly converted into MoS2crystallites after sulfidation treatment, and the local ordered structure is shrunken with the increase in Rh loading. The incorporation of rhodium shows high performance of alcohol synthesis from carbon monoxide hydrogenation.
