Activation of Gold on Titania: Adsorption and Reaction of SO2 on Au/TiO2(110)
TL;DR: The experimental and theoretical results show quite clearly that not only gold is perturbed when gold and titania interact, but the adsorbed gold enhances the reactivity of titania by facilitating the migration of O vacancies from the bulk to the surface of the oxide.
Journal ArticleDOI
Chemistry of NO2 on oxide surfaces: formation of NO3 on TiO2(110) and NO2 O vacancy interactions.
TL;DR: The behavior of the NO(2)/titania system illustrates the importance of surface and subsurface defects when using an oxide for trapping or destroying NO(x)() species in the prevention of environmental pollution (DeNOx operations).
Journal ArticleDOI
Chemistry of sulfur-containing molecules on Au(111): thiophene, sulfur dioxide, and methanethiol adsorption
TL;DR: In this paper, thermal desorption spectroscopy (TDS) and synchrotron-based high-resolution soft X-ray photoelectron spectrographs were used to study the interactions of three sulfur-containing molecules (C 4 H 4 S, SO 2, CH 3 SH) with a clean Au(1, 1, 1) surface.
Journal ArticleDOI
Interaction of SO 2 with CeO 2 and Cu/CeO 2 catalysts: photoemission, XANES and TPD studies
José A. Rodriguez,Tomas Jirsak,Andrea Freitag,Jonathan C. Hanson,John Z. Larese,Sanjay Chaturvedi +5 more
TL;DR: In this article, the results of XANES and photoemission provide evidence that SO4 was formed upon the adsorption of SO2 on pure powders or films of CeO2 at 300 K. The sulfate decomposed in the 390-670 K temperature range with mainly SO2 and some SO3 evolving into gas phase.
Journal ArticleDOI
Chemistry of NO2 on CeO2 and MgO: experimental and theoretical studies on the formation of NO3
TL;DR: In this article, Synchrotron-based x-ray absorption near-edge spectroscopy, high-resolution photoemission, and first-principles density functional calculations (DFT-GGA) were used to study the interaction of nitrogen dioxide with CeO2 and MgO.
