Quantifying interactions on interfaces between metal particles and oxide supports in catalytic nanomaterials

Publikováno v: Dipòsit Digital de la UB

Metal-support interactions can dramatically affect the properties of nanocomposite materials. Nevertheless, comprehensive studies of the interfaces between metal nanoparticles and oxide supports remain scarce due to challenges in experimental charact

Here we show, combining CO stripping voltammograms on different PtCu nanoparticle (NP) low-temperature fuel cell electrocatalysts and density functional calculations, that surface chemical ordering and the presence of certain defects explain the CO t

Stability of oxidized states of ceria-supported PtOx particles under a wide range of gas-phase conditions

Autor: Jon Eunan Quinlivan Domínguez, Konstantin Neyman, Albert Bruix

Nanostructured materials based on non-inert oxides CeO2 and PtyOx play a fundamental role in catalyst design. However, their characterization is often challenging due to their structural complexity and the tendency of the materials to change under re

Systematic Density Functional Study of the Adsorption of Transition Metal Atoms on the MgO(001) Surface

Autor: and Konstantin Neyman, Gianfranco Pacchioni, Notker Rösch, Ilya V. Yudanov

Publikováno v: Scopus-Elsevier

We report the results of nonrelativistic and relativistic gradient-corrected density functional calculations on the interaction of single transition metal atoms with the oxygen sites of the regular MgO(001) surface. The surface has been represented b
