Journal ArticleDOI
Electron spectroscopy of single crystal and polycrystalline cerium oxide surfaces
TL;DR: In this paper, the binding energy peaks in the O 1s XAS spectrum were identified for oxidized and sputtered single crystal CeO 2 films and for oxidised Ce foil, and features were identified that distinguish between the Ce 4+ or Ce 3+ oxidation states.
Journal ArticleDOI
CO Oxidation on Supported Single Pt Atoms: Experimental and ab Initio Density Functional Studies of CO Interaction with Pt Atom on θ-Al2O3(010) Surface
Melanie Moses-DeBusk,Mina Yoon,Lawrence F. Allard,David R. Mullins,Zili Wu,Xiaofan Yang,Gabriel M. Veith,G. Malcolm Stocks,Chaitanya K. Narula +8 more
TL;DR: The results clearly show that supported Pt single atoms are catalytically active and that this catalytic activity can occur without involving the substrate.
Journal ArticleDOI
The surface chemistry of cerium oxide
TL;DR: In this paper, a review of the structure and chemical reactions on well-defined cerium oxide surfaces is presented, and the growth, characterization and properties of these thin-films are also examined.
Journal ArticleDOI
Ordered cerium oxide thin films grown on Ru(0001) and Ni(111)
TL;DR: In this article, a 1-10-ML thin film was grown on the Ru(0001) and Ni(111) surfaces with an orientation determined by the orientation of the substrate on which they were grown.
Journal ArticleDOI
Thiolate ligands as a double-edged sword for CO oxidation on CeO2 supported Au25(SCH2CH2Ph)18 nanoclusters.
Zili Wu,De-en Jiang,Amanda K. P. Mann,David R. Mullins,Zhen-An Qiao,Lawrence F. Allard,Chenjie Zeng,Rongchao Jin,Steven H. Overbury +8 more
TL;DR: Isotopic labeling experiments clearly indicate that CO oxidation on the Au25(SR)18/CeO2 rod catalyst proceeds predominantly via the redox mechanism where CeO2 activates O2 while CO is activated on the dethiolated gold sites.
