Title:
Cluster Size-Dependent Mechanisms of the CO + NO Reaction on Small Pdn (n ≤ 30) Clusters on Oxide Surfaces 
Abstract:
The CO + NO reaction (2CO + 2NO → N2 + 2CO2) on small size-selected palladium clusters supported on thin MgO(100) films reveals distinct size effects in the size range Pdn with n ≤ 30. Clusters up to the tetramer are inert, while larger clusters form CO2 at around 300 K, and this main reaction mechanism involves adsorbed CO and an adsorbed oxygen atom, a reaction product from the dissocn. of NO. In addn., clusters consisting of 20-30 atoms reveal a low-temp. mechanism obsd. at temps. below 1...    »
