Abstract
The presence of barium (θca. 0.1) at a Zn(0001) surface is shown to increase the rate of dioxygen bond cleavage by ca. 103 at 295 K; this provides further evidence for a mobile molecular precursor O2 –(s) participating in the dynamics of the dissociative chemisorption of oxygen and first suggested by the probe-molecule approach used to search for transient surface oxygen states.Keywords
