High-pressure in situ FR-IR spectroscopic techniques were applied to study the surface species on SiO/sub 2/-supported Rh-Fe catalysts which efficiently catalyze the formation of methanol and ethanol in the prevailing pressured Co-H/sub 2/ reaction. Three different related oxygenate species, e.g., methoxy, ethoxy, and acyl, which are bonded to Rh and/or Fe, have been proposed as the surface intermediates. The interpretation of the surface structures has been discussed in terms of the band shifts corresponding to the deuterated species formed in the CO-D/sub 2/ reaction on the catalyst. 19 references, 3 figures, 1 table.
