  Adsorption of CO on the catalytic system K-5[SiW11RhO39]/Al2O3 was studied by diffuse-reflectance IR spectroscopy. The electronic state of rhodium and thermal stability of the system in the redox cycles were studied. The oxidized heteropolycompound (HPC) contains the charged forms Rh+, Rh2+, and Rh3+. Their ratio strongly depends on the pre-treatment temperature of the sample. In the reduced HPC two main forms of rhodium exist: the ionic Rh+ and metallic Rh-0. The supported HPC structure is stable in an oxidative medium at temperatures below -900 K. The properties of the K-5[SiW1 1RhO39]/Al2O3 system are retained in the redox cycles up to -670 K, and the highly dispersed state of rhodium is observed up to 900 K.
