The hydrogenation of CO over supported rhodium (Rh) films has been investigated by using ir spectroscopy as a probe. Rhodium loading and support material were variables in this work. Data for 0.5 wt % Rh/X (X = titanium oxide, silica, alumina (TiO/sub 2/, Al/sub 2/O/sub 3/,SiO/sub 2/) films have been interpreted to indicate that a rhodium monocarbonyl hydride species is an important intermediate in catalytic methanation in agreement with an earlier proposal by Solymosi and co-workers. A support effect was evident with Rh/TiO/sub 2/ films being more active for catalytic hydrogenation of CO than were Rh/Al/sub 2/O/sub 3/ or Rh/SiO/sub 2/ films. 2 figures, 1 table.
