On the Oxidation of Palladium clusters supported on alumina/NiAl(110)

ORAL

Abstract

Palladium nanostructures supported on alumina substrates have been widely studied as catalysts for several combustion processes. Following recent experimental results [1], we have performed electronic structure density functional calculations in order to study the geometry, stability and electronic properties of small Pd clusters supported on alumina/NiAl(110). Using an accurate model of such surface, the properties of selected cluster sizes have been determined, as well as the effect of the addition of oxygen. A carefully analysis of the results as well as a comparison with the experimental data will be presented. \\[4pt] [1] T.Wu et al, Surface Science 603, 2764 (2009).
