Using p-MBRS experiments and TPR as well as FTIR measurements, it could be shown that dissociative oxygen activation occurs in the same temperature range for small clusters in comparison to faceted nanoparticles (NPs) and Pd single crystals. Surprisi

Simulations of cluster-based catalytic oxidation of CO were performed using a dual reverse spill-over microkinetic model (DRSO-MK simulations) in order to improve the description and understand the underlying physics of the experimental turn-over dat

The catalysed oxidation of CO using mass-selected Pd(13) clusters supported on thin MgO films was modelled using a microkinetic simulation of the reaction. The model of the system includes reverse spill-over calculations which were intrinsically inco
