The reaction of carbon monoxide and oxygen over supported rhodium films has been studied using infrared spectroscopy. The focus of work was the reactivity of the various CORhX XAl2O3, SiO2, TiO2 surface states for supported catalysts having high and low Rh loading. Under the reaction conditions the linear CO species was the most stable toward oxidation, but this could have been a result of an oxidized Rh surface. A new CORh surface species has been proposed which exhibits an infrared band at 2000cm for a 0.5 RhTiO2 film. This species is believed to be a bridged carbonyl between Rh1 and the TiO2 support. Originator-supplied keywords include Infrared spectroscopy, and Carbon dioxide.
