The present paper describes experimental findings concerning non-linear behaviour in the NO–H2 reaction over Ir(110). To our knowledge, this is the first report of catalytic rate oscillations over Ir(110). The oscillatory behaviour was obtained in the 10−6 mbar NO pressure regime around 475 K in a large excess of hydrogen. The N2 production rate oscillates out of phase with the rates of NH3 and H2O formation. No N2O was formed under the conditions examined. The oscillatory behaviour found over Ir(110) is compared with those reported earlier for Pt(100) and Rh single crystal surfaces.
