abstract = {Vehicles that run on natural gas must be equipped with an
exhaust gas after-treatment system to burn their unavoidable
CH4 slip, which must not be released into the environment as
CH4 is a potent greenhouse gas. Pd is known as a highly
active catalyst material for CH4 oxidation. For this study,
Pd was deposited on a γ-Al2O3 support and the as-received
samples were pre-reduced and pre-oxidized, respectively.
Near-Ambient Pressure Photoelectron Spectroscopy and the
Temporal Analysis of Products methodology were combined to
understand that both electronic states, namely PdO and Pd°,
are active for the CH4 oxidation reaction, whereby the
superior activity of the pre-reduced Pd/γ-Al2O3 catalyst
was ascribed to the spill-over of OH-groups from the support
to Pd. It was found that the reaction products, CO, CO2 and
H2, were strongly and, to a large extent, adsorbed on the
catalyst surface and were involved in reversible chemical
interactions on the catalyst surface during the CH4
oxidation reaction on the Pd/γ-Al2O3 catalyst.},
