Abstract

The influence of the oxygen induced surface reconstructions on the CO₂ production rate at the Ag(110)-O system will be discussed, based on titration, reactive thermal desorption and LEED measurements. We present evidence that the reactivity of oxygen is reduced in the temperature range of 190–250 K by embedding oxygen in a reconstructed surface as compared to chemisorbed oxygen; above 250 K the coverage dependence of the oxygen induced reconstructions generates an autocatalytic component into the CO₂ formation rate.
