The formation of the Rh{sup I} ion during CO chemisorption on Rh/Al{sub 2}O{sub 3} catalysts has been directly observed using UV-visible spectroscopy. Comparison of infrared and UV-visible spectra indicates that the species Rh{sup I}(CO){sub 2} is produced by a surface oxidation process operating on metallic Rh{sup 0} sites and involving Al-OH groups as oxidizing centers, in agreement with previous postulates.
