CO2 Hydrogenation for C2+ Alcohols Synthesis over Silica-Supported Ir-Mo Catalysts

Abstract CO2 hydrogenation over silica-supported catalysts was carried out to investigate the synthesis of C2+ alcohols (ethanol, propanol and butanol). The Ir-Mo bimetallic system among the catalysts investigated was found to produce C2+ alcohols. The catalytic performance of the Ir-Mo catalysts was examined as a function of Mo/Ir molar ratio. It was revealed that the highest selectivity to C2+ alcohols was obtained in the Mo/Ir ratios of around 0.3.
