We have measured the dissociative chemisorption probability of D2 on Pt ( I 1 I ) as a function of molecular oxygen coverage and have found that the dissociation probability decreases linearly with O2 coverage. The results suggest that O2 poisons the chemisorption sterically by blocking approximatel
Photoinduced dissociation of O2 molecules on Pd( ) is assumed to occur via trapping of photoexcited hot metal electrons to an empty adsorbate resonance. As the excited state formed may decay back, the dissociation cross section is proportional to the survival probability of this state. The survival
