Abstract:

An infrared study has been performed concerning the possible dissociation of CO2 on supported Rh catalyst films. The data indicate that CO2 does dissociate on RhTiO2 and RhAl2O3 to form a carbonyl hydride species in accord with the work of Solymosi. This dissociation process is considerably enhanced by the presence of a small amount of hydrogen gas, but will proceed in the absence of hydrogen gas with the assistance of hydrogen migration from the support. Impurity boron also enhances the formation of the carbonyl hydride species, and hence CO2 dissociation, when it is present in the supported Rh films.
