Dynamics of the oxygen combination reaction on Pt(111) initiated by photodissociation of N2O at 193 nm: O*+O(ad)→O2(g)

Abstract
The desorption of O2 is observed when a Pt(111) surface with the coadsorbates of oxygen atoms and N2O is irradiated with 193 nm photons. This indicates that an oxygen atom produced by photodissociation of N2O reacts with a chemisorbed oxygen adatom to form an oxygen molecule. The dynamics of the photoinitiated combination reaction of oxygen is studied by time‐of‐flight spectroscopy.
