An Infrared Study of the Oxidation of Carbon Monoxide over Supported Rhodium Catalysts.

Abstract

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 CO/Rh/X (X=Al2O3, 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 CO/Rh surface species has been proposed which exhibits an infrared band at 2000/cm for a 0.5% Rh/TiO2 film. This species is believed to be a bridged carbonyl between Rh+1 and the TiO2 support. Originator-supplied keywords include: Infrared spectroscopy, and Carbon dioxide.
