Gold, Copper, and Platinum Nanoparticles Dispersed on CeO/TiO(110) Surfaces: High Water-Gas Shift Activity and the Nature of the Mixed-Metal Oxide at the Nanometer Level.

At small coverages of ceria on TiO(110), the CeO nanoparticles have an unusual coordination mode. Scanning tunneling microscopy and density-functional calculations point to the presence of CeO dimers, which form diagonal arrays that have specific orientations of 0, 24, and 42° with respect to the [1...
