This book was released on 1985 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Rh/TiO2 and Rh/Al2O3 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. Author finished keywords: Infrared spectroscopy, Carbon dioxide, Methanation, Supported rhodium catalysts.

This book was released on 1985 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: An infrared study of the methanation of CO2 on supported Rh catalysts has been performed. This reaction has been shown to occur over these catalysts with higher turnover frequency at a given temperature and Rh loading than does the methanation of CO. A support effect has been demonstrated for the reaction over the supported Rh catalysts (TiO2 Al2O3 SiO2 in reactivity). A key surface intermediate during the methanation reaction is a carbonyl hydride species, as evidenced by a prominent infrared band in the 2020-2040/cm region which shifts by 5-10/cm when D2 is substituted for H2 in the reaction mixture. This carbonyl hydride species can be produced in the absence of H2 by migration of H from the support to Rh. The dissociation of CO2 on supported Rh has been shown to be enhanced by the presence of H2 and impurity boron. Originator-supplied keywords include: Infrared spectroscopy, Carbon dioxide, Hydrogenation, Methanation, and Supported rhodium catalysts.

Download or read book An Infrared Study of the Oxidation of Carbon Monoxide Over Supported Rhodium Catalysts written by C. H. Dai and published by . This book was released on 1985 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book An Infrared Study of Isotopic Exchange During Methanation Over Supported Rhodium Catalysts; An Inverse Spillover Effect written by M. A. Henderson and published by . This book was released on 1985 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infrared spectroscopy has been employed to study the reduction of carbon dioxide on supported catalyst films. The investigation included isotopic labeling using deuterium as the reduction gas. Isotopic exchange was observed for both carbon dioxide/D2 and methane/deuterium mixtures. The mechanism of this isotopic exchange involves migration of hydrogen from the support to the rhodium sites, an inverse spillover effect. A key intermediate in the dissociation of carbon dioxide on the supported Rh films was a carbonyl hydride species.
