The decomposition of NO to N2 and O2 on nanosized platinum and palladium facets is investigated with field ion microscopy experiments.  Corresponding density functional theory calculations are performed.  The presence of an external field is shown to facilitate this reaction pathway through the formation of a (NO)2 dimer.
