Abstract Self-sustained isothermal oscillations in the NO–H 2 reaction were found on the Ir(110) surface. The rates of NH 3 and N 2 formation oscillate exactly out of phase. The high activity state during the oscillations (high NO conversion) corresponds to a high rate of NH 3 formation, while in the low activity state a high rate of N 2 formation has been observed. The shape of the oscillations is very sensitive to changes in the H 2 /NO ratio or temperature. Build-up of a stable N species… CONTINUE READING
