CO, DISSOCIATION ON RHODIUM: MEASUREMENT OF THE SPECIFIC RATES ON Rh( 111) *
نویسندگان
چکیده
The measured rates for CO, dissociation on Rh(ll1) are reported for a Ha/CO, reaction mixture at a total pressure of 100 Torr and a CO, partial pressure of 1 Torr. The activation energy associated with the conversion of CO, to CO is 17 kcal/mol. The reaction probabilities for CO, dissociation range from 10-s at 750 K to 10-s at 444 K. The probability of CO, dissociation on Rh(ll1) is shown to be on the order of lo-” at 300 K rather than the previously reported value near 10-l.

Computational study of the adsorption and dissociation of phenol on Pt and Rh surfaces.
The adsorption of phenol on flat and stepped Pt and Rh surfaces and the dissociation of hydrogen from the hydroxyl group of phenol on Pt(111) and Rh(111) were studied by density functional calculations. On both Pt(111) and Rh(111), phenol adsorbs with the aromatic ring parallel to the surface and the hydroxyl group tilted away from the surface. Furthermore, adsorption on stepped surfaces was co...
متن کاملAdsorption of CO on V-Rh(111)(2×2) Surface
We prepared a new V-Rh(111) alloy with (2×2) surface geometry. The alloy system and the adsorption of CO were investigated by the photoelectron spectroscopy of the valence and core states using synchrotron radiation, and by temperature-programmed thermal desorption spectroscopy (TPD). The obtained results indicate that the vanadium atoms in the prepared alloy were situated mainly in the subsurf...

Optical infrared-visible sum-frequency generation (IR-VIS SFG) surface vibrational spectros-copy was employed for in situ detection of chemisorbed CO during CO adsorption and catalytic CO oxidation on a rhodium (111) catalyst in the substrate temperature range T s = 300– 800 K. CO adsorption studies performed over 12 orders of magnitude in CO pressure (p CO = 10-8 –1000 mbar) demonstrated the r...
متن کاملA reactive oxide overlayer on rhodium nanoparticles during CO oxidation and its size dependence studied by in situ ambient-pressure X-ray photoelectron spectroscopy.
Carbon monoxide oxidation is one of the most studied heterogeneous reactions, being scientifically and industrially important, particularly for removal of CO from exhaust streams and preferential oxidation for hydrogen purification in fuel-cell applications. The precious metals Ru, Rh, Pd, Pt, and Au are most commonly used for this reaction because of their high activity and stability. Despite ...
متن کاملStep enhanced dehydrogenation of ethanol on Rh
We have investigated the adsorption and decomposition of ethanol on the Rh(111) and Rh(553) surfaces at room temperature with special emphasis on the dehydrogenation. We use high resolution core level photoemission and density functional theory (DFT) based simulations. A detailed analysis of the C1s core level spectra, including analysis of the vibrational fine-structure and comparison to calcu...
