Research Abstract |
The structure of dissociating intermediate N_2O in the catalyzed NO reduction on stepped Pd(211)=[(s)3(111)×(001)] has been examined from the spatial distribution of emitted N_2 and DFT-GGA model calculations. The active N_2O is adsorbed through the terminal N on a (111) terrace and its dissociation is completed by the terminal oxygen removal onto stepped Pd atoms. The N_2 emission is concentrated along the rupture bond axis, i.e., in the plane along the step up-and-down direction.
