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

## Abstract Catalysts were prepared from ultra pure SiO~2~, Pd and Rh nitrates and chlorides, and by doping with Al, Fe, Na, K or Ca nitrate. The activities and selectivities of the Pd and Rh catalysts were investigated in CO hydrogenation at 553K, H~2~/CO = 2 or 3, and 2.5 or 4 MPa, respectively.
