Hydrogenation of CO, to ethanol was carried out over Rh/SiO, based catalysts. The main product over the unpromoted catalysts was methane. By adding various metal oxide promoters to the catalysts, CO, conversion and selectivity to alcohols (methanol and ethanol) increased. Among the promoters, Li sal
