Abstract

The hydrogenation of CO₂ was investigated with SiO₂-supported Ir-Mo bimetallic catalysts. The C₂⁺ alcohols (ethanol, 1-propanol and 1-butanol) were found to be formed by the synergistic action of Ir and Mo. The CO₂ conversion was dependent upon metal impregnation procedures and Mo/Ir molar ratios, but the selectivity to C₂⁺ alcohols was almost constant regardless of these factors. Iridium-Mo/SiO₂ catalysts exhibited the highest CO₂ conversion and yield of C₂⁺ alcohols at a Mo/Ir ratio of about 0.3. The results obtained in this work are similar to those in the CO hydrogenation with Ir-Mo/SiO₂ catalysts. As a result, it is suggested that the active species of Ir-Mo/SiO₂ catalysts might be the same both in the CO₂ hydrogenation and in the CO hydrogenation.
