Role of support in adsorption and catalysis on supported metals. I. IR spectroscopic study of adsorption of CO and H/sub 2/ on Rh/SiO/sub 2/, Rh/Al/sub 2/O/sub 3/, and Rh/La/sub 2/O/sub 3/

With the aim of studying the influence of the nature of the support on the properties of supported rhodium-containing catalysts, the adsorption of CO and H/sub 2/ on Rh/SiO/sub 2/, Rh/Al/sub 2/O/sub 3/, and Rh/La/sub 2/O/sub 3/ has been investigated. It has been found that in the case of Rh/La/sub 2/O/sub 3/, along with the surface complexes that are characteristic for Rh/SiO/sub 2/ and Rh/Al/sub 2/O/sub 3/, new surface compounds of adsorbed CO and H/sub 2/ are formed. On the basis of an analysis of the spectrochemical properties of these boundary with the participation of the metal atoms and also the atoms of the support.
