Dissociative chemisorption on metal surface

Abstract

Quantum dynamics studies of dissociative chemisorption of diatomic molecules on metal surfaces have revealed some interesting features that may have important potential applications. The probability for dissociative adsorption of a diatomic molecule on relatively smooth metal surfaces is highly dependent on rotational orientation of the diatomic molecule with the parallel (helicopter) mode being most favorable in overcoming the dissociation barrier. For dissociation of homonuclear diatoms under certain conditions, there is a selection rule which forbids the dissociation of the molecule at low collision energies. In the model simulation of dissociation probability with a time-dependent barrier, the dissociation probability is found to have a maximum as a function of the oscillating frequency of the barrier.
