CO2 HYDROGENATION FOR C-2-SUPPORTED IR-MO CATALYSTS( ALCOHOLS SYNTHESIS OVER SILICA)

CO2 hydrogenation over silica-supported catalysts was carried out to i nvestigate the synthesis of C-2+, alcohols (ethanol, propanol and buta nol). The Ir-Mo bimetallic system among the catalysts investigated was found to produce C-2+ alcohols. The catalytic performance of the Ir-M o catalysts was examined as a function of Mo/Ir molar ratio. It was re vealed that the highest selectivity to C-2+ alcohols was obtained in t he Mo/Ir ratios of around 0.3.
