Book Characterization and Reaction Studies of Silica Supported Platinum and Rhodium Model Catalysts

Download or read book Characterization and Reaction Studies of Silica Supported Platinum and Rhodium Model Catalysts written by Matthew James Lundwall and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The physical and catalytic properties of silica supported platinum or rhodium model catalysts are studied under both ultra high vacuum (UHV) and elevated pressure reaction conditions (>1torr). Platinum or rhodium nanoparticles are vapor deposited onto a SiO2/Mo(112) surface and characterized using various surface analytical methods. CO chemisorption is utilized as a surface probe to estimate the concentration of various sites on the nanoparticles through thermal desorption spectroscopy (TDS) and infrared reflection absorption spectroscopy (IRAS) along with microscopy techniques to estimate particle size. The results are compared with hard sphere models of face centered cubic metals described as truncated cubo-octahedron. Results demonstrate the excellent agreement between chemisorption and hard sphere models in estimating the concentration of undercoordinated atoms on the nanoparticle surface. Surfaces are then subjected to high pressure reaction conditions to test the efficacy of utilizing the rate of a chemical reaction to obtain structural information about the surface. The surfaces are translated in-situ to a high pressure reaction cell where both structure insensitive and sensitive reactions are performed. Structure insensitive reactions (e.g. CO oxidation) allow a method to calculate the total active area on a per atom basis for silica supported platinum and rhodium model catalysts under reaction conditions. While structure sensitive reactions allow an estimate of the types of reaction sites, such as step sites ([less than or equal to]C7) under reaction conditions (e.g. n-heptane dehydrocyclization). High pressure structure sensitive reactions (e.g. ethylene hydroformylation) are also shown to drastically alter the morphology of the surface by dispersing nanoparticles leading to inhibition of catalytic pathways. Moreover, the relationships between high index single crystals, oxide supported nanoparticles, and high surface area technical catalysts are established. Overall, the results demonstrate the utility of model catalysts in understanding the structure-activity relationships in heterogeneous catalytic reactions and the usefulness of high pressure reactions as an analytical probe of surface morphology.

Book An Infrared Study of the Oxidation of Carbon Monoxide Over 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.
