Title: The Interaction of Carbon Monoxide with Rhodium on Potassium-Modified CeO₂(111)

Abstract

The adsorption and reactions of CO adsorbed on Rh particles deposited on K-covered CeO₂(111) were studied by temperature programmed desorption and photoelectron spectroscopy. K deposited on CeO₂(111) forms a KO_X over-layer by extracting O from the ceria and partially reducing some of the Ce⁴⁺ to Ce³⁺. CO does not adsorb on the KO_X / CeO_2-X(111) surface in the absence of Rh particles. CO adsorbed on Rh / K / CeO₂(111) adsorbs molecularly on the Rh at 200 K. As the surface is heated the CO spills-over and reacts with the KOX to form carbonate. The carbonate decomposes at elevated temperature to produce CO and CO₂. The carbonate stabilizes the KO_X so that K desorbs at a higher temperature than it would in the absence of CO. When the Rh and K deposition are reversed so that K is deposited on both the Rh and the CeO²(111), CO adsorbs as CO^2- at 200 K. The CO^2- decomposes below 350 K to produce gas phase CO and adsorbed CO3^2- and CO. The CO is stabilized by the K on the Rh and desorbs above 540 K. The carbonate decomposes into gas phase CO and CO₂.

High-resolution electron energy loss spectroscopy study of the surface structure of benzene adsorbed on the rhodium(111) crystal face

Journal Article Koel, B E ; Crowell, J E ; Mate, C M ; ... - J. Phys. Chem.; (United States)

Benzene adsorption on the Rh(111) crystal surface has been studied by HREELS (high-resolution electron energy loss spectroscopy), LEED (electron diffraction), and TPD (temperature programmed desorption). The vibrational spectra indicate that benzene adsorbs molecularly at 300 K and is ..pi..-bonded to the surface with the ring plane parallel to the surface plane. Recent dynamic LEED calculations together with the angle-dependent HREELS studies reported here establish a C/sub 3v/(sigma/sub d/) bonding symmetry for the c(2..sqrt..3 x 4)rect-C/sub 6/H/sub 6/ structure. Several other ordered benzene overlayers can be formed between 300 and 400 K depending on the benzene coverage. No large changes occurmore »« less

Studies of the coadsorption of deuterium and carbon monoxide with silver on rhodium and the adsorption of 2,4,6-trinitrotoluene on clean and carbon covered platinum

Thesis/Dissertation Peebles, H C

Ag adsorbed on Rh(100) is presented as a model of the corresponding bimetallic catalyst. Ag overlayer growth follows the Frank-Van der Merwe growth mechanism at 300 K and the Stranski-Krastanov growth mechanism at 640 K. Ag(3d) binding energies are found to track the vacuum level rather than the Fermi level. The results of D/sub 2/ and CO adsorption studies on Ag/Rh(100) show that adsorbed Ag does not significantly alter the properties of adjacent D/sub 2/ or CO adsorption sites on the Rh(100) surface. The desorption and decomposition of 2,4,6-trinitrotoluene (TNT) on clean and carbon covered Pt(111) is also reported. Nomore »« less
Activity of Rh{sup x+} species in CO oxidation and NO reduction in a CO/NO/O{sub 2} stoichiometric mixture over a Rh/CeO{sub 2}-ZrO{sub 2} catalyst

Journal Article Fajardie, F ; Blanchard, G ; Tempere, J F ; ... - Journal of Catalysis

The catalytic activity of a 0.30 wt% Rh/CeO{sub 2}-ZrO{sub 2} catalyst (25% ZrO{sub 2} in weight) 188 m{sup 2}/g was studied in the oxidation of CO and reduction of NO in a CO/NO/O{sub 2} stoichiometric mixture, in the temperature range of 298--773 K. The hydrogenation of benzene, a structure insensitive reaction was used for counting surface Rh(0) atoms after either thermal treatment of the catalyst in hydrogen at 773 K, or reduction by the stoichiometric CO/O{sub 2}/NO reaction mixture. The bibliography shows that the turnover rate over RH{sup x+} is lower than that over Rh(0) by two orders of magnitude.more »« less

Growth, sintering, and chemical states of Co supported on reducible CeO₂(111) thin films: The effects of the metal coverage and the nature of the support

Journal Article Zhou, Jing ; Du, Linze ; Braedt, Daniel L. ; ... - Journal of Chemical Physics

The growth, sintering, and interaction of cobalt with ceria were studied under ultrahigh vacuum conditions by vapor-deposition of Co onto well-defined CeOx(111) (1.5 < x < 2) thin films grown on Ru(0001). Charge transfer from Co to ceria occurs upon deposition of Co on CeO_1.96 and partially reduced CeO_1.83 at 300 K. X-ray photoelectron spectroscopy studies show that Co is oxidized to Co²⁺ species at the cost of the reduction of Ce⁴⁺ to Ce³⁺, at a lesser extent on reduced ceria. Co²⁺ is the predominant species on CeO_1.96 at low Co coverages (e.g., ≤0.20 ML). The ratio of metallic Co/Co²⁺more »« less

Infrared reflection absorption spectroscopy and temperature-programmed desorption studies of CO adsorption on Ni/CeO₂(111) thin films: The role of the ceria support

Journal Article Peterson, Erik W. ; Wang, Huanru ; Liu, Zongyuan ; ... - Journal of Vacuum Science and Technology A

Ceria-supported Ni has shown unique catalytic activity due to unique properties of small Ni particles and strong metal-support interaction. Identification of adsorption sites and understanding the chemical interaction over Ni-ceria at the fundamental level provide crucial insights into the reaction pathways of complex catalytic processes. In this study, to probe the surface sites, the adsorption of CO was carried out with model Ni/ceria systems consisting of Ni nanoparticles vapor-deposited on well-ordered CeO_x(111) (1.5 < x < 2) thin films using infrared reflection absorption spectroscopy (IRRAS) and temperature-programmed desorption (TPD) under ultrahigh vacuum (UHV) conditions.
