Infrared spectroscopy study of adsorption and coadsorption of carbon monoxide and hydrogen on Ru/Al203

Infrared spectroscopy study of adsorption and coadsorption of carbon monoxide and hydrogen on... IR spectroscopy was used to study CO adsorption and coadsorption with H2 on 5% Ru/Al2O3. By variation of sample pretreatment, CO pressures, contact time and temperature several surface species were identified: mono– and multicarbonyl species formed with ruthenium in different oxidation state and on various sites of the catalyst surface. During CO and H2 coadsorption and interaction, a new band at 2030 cm–1 was registered. It was assigned to a 'hydrocarbonyl' species on the metal particles. Thermal stability of some CO species was studied. Most stable and least reactive species was found to be a multicarbonyl giving rise to bands at 1980 and 2060 cm–1. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
